Genetic algorithm with solution of pde toolbox
Hi I’m on project that find optimal parameter about transient heat transfer problem. (find optimal values that minimize temperature fluctuation)
I have problem about exceed maximum array size (about 1800GB) while solving ga problem
I defined a design domain contains multiple values (i.e. length, geometry properties, etc) and FEA using pde toolbox has finished
the last task what i have to do is find optimal values with solution of FEA using ga function and my pseudo code about FEA is here:
function [result, model] = Heattransfer(L1, t1, t2, t3, length_fin, num_fins, shelltype, shellmat, intermed, time)
thermalmodel = createpde(‘thermal’, ‘transient’);
tlist = 0:1:time*60*60;
% Skip code about geometries, BC, IC
result = solve(thermalmodel, tlist);
model = thermalmodel;
end
L1, t1, t2, t3, length_fin is about geometry parameters that is noninteger values (because it is length)
num_fins, shelltype, shellmat, intermed is also about geometry parameters that is interger values (because it is about number or material type, i implemented that decide material type, geometry type by select number like if shellmat == 1, steel / elseif shellmat == 2, polymer)
and code about ga is as below:
function value = ObjectiveFcn(a, time)
L1 = a(1);
t1 = a(2);
t2 = a(3);
t3 = a(4);
length_fin = a(5);
num_fins = a(6);
shelltype = a(7);
shellmat = a(8);
intermed = a(9);
result = Heattransfer(L1, t1, t2, t3, length_fin, num_fins, shelltype, shellmat, intermed, time);
T = result.Temperature;
std_dev = std(T, 0, 1);
value = mean(std_dev);
end
function [c, ceq] = Constraints(b)
L1 = b(1);
t1 = b(2);
t2 = b(3);
t3 = b(4);
length_fin = b(5);
c1 = L1 + t1 + t2 + t3 – 0.3; % 0.3 is total length of control volume
c2 = length_fin – t1;
c3 = length_fin – t3;
c = [c1; c2; c3];
ceq = [];
end
% a = [L1, t1, t2, t3, length_fin, num_fins, shelltype, shellmat, intermed]
lb = [0, 0, 0, 0, 0, 1, 1, 1, 1];
ub = [0.3, 0.01, 0.02, 0.01, 0.01, 374, 2, 3, 2];
intvar = [6, 7, 8, 9];
ObjectivefunWithTime = @(a) Objectivefun(a, time);
ConstraintsFcn = @(b) Constraints(b);
options = optimoptions(‘ga’, ‘Display’, ‘iter’, ‘PopulationSize’, 10,…
‘MaxGenerations’, 20, ‘CrossoverFraction’, 0.8, ‘UseParallel’, true);
[x_opt, fval] = ga(ObjectivefunWithTime, 9, [], [], [], [], lb, ub, ConstraintsFcn, intvar, options);
time is not design variable so I excepted it from objective function
In ub (upper bound), I actually want to set value for t1, t2, t3, length_fin as 0.3 to find optimal value widely (under Constraints) but when i set values like that, it results error for invalid geometry (conflicted in pde toolbox code) so I defined arbiturary values.
What should I do for achieve my goal? (find optimal value)
I’m sorry for messy code
If anyone knows about this, please comment.

How does im2int16 map double(0.5) to int16(0)?
I’ve known about this for a long time, and I’ve ignored it. It’s a curiosity I pick at every time I edit MIMT imcast(), but I’ve never really figured out a good explanation.
IPT im2int16() maps floating point values on the unit interval to values on the interval [-32768 32767]. That seems very simple. The problem is that obvious arithmetic doesn’t give the same result. What’s more curious is that it seems that the only input value that does not map identically is 1/2.
% our input
dx = 3E-5;
x = [0 linspace(0.5-dx,0.5+dx,7) 1].’; % ‘single’ or ‘double’ are the same
% convert it
y1 = im2int16(x); % the curiosity
y2 = int16(double(x)*65535 – 32768); % the obvious
y3 = int16(rescale(x,-32768,32767,’inputmin’,0,’inputmax’,1)); % a third opinion
% compare
[y1 y2 y3]
For what it’s worth, im2double() doesn’t map that 0 back to 1/2. It maps exactly like one would expect.
% map back to float
z1 = im2double(y1(2:8));
z2 = ((double(y2(2:8)) + 32768)/65535 );
% compare error
[z1 z2] – x(2:8)
So I suppose I have three sorts of questions.
How does this happen? I’m assuming this rises naturally from some simple conversion being used, but im2int16() isn’t working in mcode, and I’m not the clever one here.
Do you think this should be expected? Matter of differing conventions? Preference?
Does it really even matter? I’ve been assuming it doesn’t.I’ve known about this for a long time, and I’ve ignored it. It’s a curiosity I pick at every time I edit MIMT imcast(), but I’ve never really figured out a good explanation.

But, If version number has decimal, it trys to find the whole string as a script.

Text inside the meshgrid
Hello,
I am trying to place an arbitrary text inside the meshgrid. The code is as follows:
Nx = 201; Ny = 201;
TEXT = ‘K e k’; % Text to draw
FONT_SIZE = 10; % Font size
FONT_NAME = ‘Castellar’; % Font style (you can change this to any available font)
% Create a black image
img = zeros(Ny, Nx);
% Create a figure, axes, and an image object
figure(‘Visible’, ‘off’); % Create an invisible figure
axes(‘Units’, ‘pixels’, ‘Position’, [1, 1, Nx, Ny], ‘Visible’, ‘off’); % Create axes
imageHandle = imshow(img); % Show the black image
% Add text to the image
text(Nx / 2, Ny / 2, TEXT, ‘FontSize’, FONT_SIZE, ‘FontName’, FONT_NAME, …
‘Color’, [1, 1, 1], ‘HorizontalAlignment’, ‘center’, ‘VerticalAlignment’, ‘middle’);
% Get the image data
frame = getframe(gca);
imgWithText = frame.cdata;
% Convert to grayscale and then to binary mask
imgWithTextGray = rgb2gray(imgWithText);
mask = imgWithTextGray > 0;
% Invert the binary mask
mask_inverted = ~mask;
% Convert the inverted binary mask to double type
mask_double = double(mask_inverted);
% Flip upside down
obst = flipud(mask_double);
% Display the final mask (optional)
figure;
imshow(obst);
The code works fine with this grid resolution. However, when i increase the number of mesh points along y-axis (Ny), i get incorrect size of the obst. In particular, the maximum resolution of Ny is 420. For example, if i set Nx=601 and Ny=601, i will get the obst size of 420×601. Obviously, the problem is in this part:
% Get the image data
frame = getframe(gca);
imgWithText = frame.cdata;
I cannot understand why the frame data is limited along y-axis (Ny) by 420 points despite i have enough memory. Can someone suggest anything to fix this problem?
kind regards,

imshow(obst);
The code works fine with this grid resolution. However, when i increase the number of mesh points along y-axis (Ny), i get incorrect size of the obst. In particular, the maximum resolution of Ny is 420. For example, if i set Nx=601 and Ny=601, i will get the obst size of 420×601. Obviously, the problem is in this part:
% Get the image data
frame = getframe(gca);
imgWithText = frame.cdata;
I cannot understand why the frame data is limited along y-axis (Ny) by 420 points despite i have enough memory. Can someone suggest anything to fix this problem?

proper namespace organisation with classes and enums
Hi Folks,
I’m curious of how to proper organise a folder structure for xx
Setting
Consider I’m developing a driver class for some DeviceA made by Manufacturer.
I assume, that I will use this DeviceA in several more Projects and I probably will get another one DeviceB, which use the same manufacturer-specific enumerated definitions of something – let`s say the volume levels will be defined as:
classdef enumVolumeLevels < uint8
enumeration
volLow (0)
volMid (50)
volHigh (100)
end
end
So I will write some kine of driver class including everything manufacturer-specific either as constants or as enumerations.
Folder Structure
So my Folderstructure will look like:
%rootfolder:
.+Manufacturer@DeviceADeviceA.m % class definition including constructor and destructor methods and some property ‘Volume’
.+Manufacturer@DeviceASomeMethod.m % Methods will be stored separately in class folder
.+ManufacturerenumVolumeLevels.m % enumeration class containing manufacturer-specific definitions of volume levels
Now if I’m going to write a setter and getter method, which both checks If the provided Value fits to the manufacturer-defined levels
classdef DeviceA
% […]
methods
%getter
function value = get.Volume(obj)
value = Manufacturer.enumVolumeLevels(50); %some dummy getter method
end
%setter
function set.Volume(obj,level)
arguments
obj
mode Manufacturer.enumVolumeLevels
end
% some dummy setter method
end
end
%[…]
end
Standalone usage
Now I’m goind to test my class from the root folder of this project.
… and works fine if I define an object of this class and assign or read the property Volume
test = Manufacturer.DeviceA(); %call constructor
test.Volume = 50; %set property to something
disp(test.Volume); % display this property
Code Refactoring
Following the initial Idea of writing this driver class to use it in several Application specific projects I will include it into root folder of ProjectA, which looks like:
%rootfolder of ProjectA:
.+Drivers+Manufacturer@DeviceADeviceA.m % class definition including constructor and destructor methods and some property ‘Volume’
.+Drivers+Manufacturer@DeviceASomeMethod.m % Methods will be stored separately in class folder
.+Drivers+ManufacturerenumVolumeLevels.m % enumeration class containing manufacturer-specific definitions of volume levels
.MyFunc.m %some script containing instancesof the DeviceA-class
But if I write MyFunc.m as follows:
function MyFunc
test = Drivers.Manufacturer.DeviceA(); % call constructor
test.Volume = 50; % set property to something
disp(test.Volume); % display this property
end
… it will fail after the 2nd line because from the setter point of view the enumeration class Manufacturer.enumVolumeLevels is not defined.
So my question is:
–> Is there a solution for organizing my namespace folders to avoid such visibility Problem?
Perhaps I’ll need to chanhe the folder structure of my Manufacturer-package or the way I use the enumeration class in my class DeviceA, but I’m completely stuck right now and have no Idea, what should be the best practice in this case,Hi Folks,

How can I use Python in Matlab for dll usage?
I am using Python inside of MATLAB to load a DLL so I can use its functionality. I have tried almost every combination of inputs to try and make this MATLAB-Python combo work, but I have been unsuccessful. I know my DLL is good because I have used it using solely python and I have also gotten it working in MATLAB using a different set of commands, but I really want to use the MATLAB/Python combo.
Below is what I am trying to do
%% Using Python
ctypes = py.importlib.import_module(‘ctypes’);
vnx = ctypes.cdll.LoadLibrary(‘file path where dll and header files are stored vnx_fmsynth.dll’);
%% Calling these fx’s don’t work!
vnx.fnLMS_SetTestMode(0)
vnx.fnLMS_GetNumDevices()
I can assure fnLMS_SetTestMode and fnLMS_GetNumDevices, are methods within the DLL but python-matlab does not want to recognize them. I have tried over 100 combinations of trying to get the DLL to function, but I simply cannot figure out the correct syntax. When I run essentially the same lines in python however, it does work, so I am obviously doing something wrong inside of matlab.
Let me show you what does work in MATLAB with out using python.. (this does require you have a C-code compiler installed on your PC).
%% Load Libraries

libfunc= libfunctions(‘vnx_fmsynth’)
%% tab complete for the lazy

libF.(libfunc{i})=libfunc{i}; % this way the auto complete from the structure’s field is the same as the library name
end
%% Calling these fx’s work!
calllib(libName, ‘fnLMS_SetTestMode’,0)
devNum=calllib(libName,libF.fnLMS_GetNumDevices)

the fnLMS_GetNumDevices function should response with ‘0’. the TestMode function doesn’t respond with anything, but it does functionally work. I have been told and have watched videos that running python inside of MATLAB works the same, but I am starting to question my presumptions. 🙁 Any and all help would be very much appreciated!!

Intel P +E or AMD for large (2000) Monte Carlo simulations
I’m about to build a new pc with running large Monte Carlo simulation in mind. I know that matlab doesn’t benefit from threading. Am I better off with an Intel 14700k 20core (8P+12E) cpu, or an AMD 7950x 16core cpu (16P) cpu.
I’m concerned that the intel chip E cores can’t perform equally well as the P cores, so that different Monte Carlo runs won’t finish about the same time.
On the other hand, by running bench(0), I see that AMD chips are really bad at linear algebra, which is another concern to me.
