I’ve tried reinstalling matlab on this computer and this also does not seem to fix thte problem. The reason for using this computer is that it has the specifications for the task desired.

Unknown variables appearing in solutions for symbolic equation solver

/ 2024-06-18 / Matlab

Hello,

I am currently trying to solve a symbolic equation for a variable and the solution I am receiving has roots of ‘z’ which was not previously defined or used in any of my equations. Here is where/how it appears:

In another case I modified the simplifcation process to attempt get a usable solution and ended up with just the variable ‘u’ which was not previously used or defined either. Is there a known reason why these variables are appearing. I’ve read that equations of the fifth degree can be hard to solve symbolically, which may be the reason for the ‘z’ in the roots but I don’t quite understand the ‘u’ solution.Hello,

fitting exponential decay help

/ 2024-06-18 / Matlab

Hi everyone,

Looking for a little bit of guidance for finding a lifetime decay for a 256×344 image. I think I’m pretty much there, but need some help. I was given the NLFit file to use for the fitting with the hint of using "fminsearch(‘NLfit1’,[y(end), 1, 1], [], delay*1e-3 – t0, data1" to find my fitting. However data1 is a matrix, and after some digging it seems I need to use an anonymous function?

I only started to use MATLAB about a week ago so I’m very new. Any help would be appreciated. I’ve attached the function file. Here is my current code:

%import function
import NLfit1.*

% Read file
load(‘test.mat’);
global FitResults

Tot_intensity = sum(Image_matrix, 3);

% Find the maximum intensity in the image
max_intensity = max(Tot_intensity, [], ‘all’);

% find threshold
twenty_percent_of_max = 0.2 * max_intensity;

% create a new image where all pixels below the threshold are set to zero
filtered_img = Tot_intensity;
filtered_img(Tot_intensity < twenty_percent_of_max) = 0;

%restricting image from 6000ps to 10000ps. Normally I would use a logical
%operator here but this was also a simple solution

delay(delay < 6000) = [];
delay(delay > 10000) = [];

%declare empty matrix
lifetime_image = zeros(256, 344);
x0 = 0;

%iterate over the image

for y = 1:size(filtered_img, 2) %columns

% only finding the lifetime constant for those pixels that are
% above the 20% threshold we set
if filtered_img(x, y) > 0

Find Transfer Function from Laplace transformation

Hi! I want to find the transfer function from a laplace transformation of a differential equation. Specifically this is the example I am working:
m = 1;
e = 0.06;
O = 25;
s = 25;
h = 1+e*s;
f = m*e*O^2;
P = e*f;

z = e*d;
%%%%%%%%%%%%%%%
syms t z u(t) e h P
f = diff(u(t),t,2) + 2*z*diff(u(t),t) + u(t) + e*(u(t))^3 – h^2 *P*cos(h*t);
F = laplace(f);
%transfer fuction
——————-
The laplace transformation gives me this:
F = e*laplace(u(t)^3, t, s) – subs(diff(u(t), t), t, 0) – s*u(0) + s^2*laplace(u(t), t, s) – 2*z*(u(0) – s*laplace(u(t), t, s)) + laplace(u(t), t, s) – (P*h^2*s)/(h^2 + s^2).

How can I resolve this? MATLAB crashes suddenly and unexpectedly when zooming, panning and resetting the view in MATLAB figures. The crash log stack trace always points to "cef_string_utf16_to_upper" function of "libcef.dll":

Multiplot Legend Item remains after line visible property put to “off”

/ 2024-06-18 / Matlab

Hi, on a previous post I was kindly showed how to "disable a plot" on a set of plots. What I actually want to do is temporarily remove it and Steven Lord suggested using the "visible" parameter
So I use a checkbox to allow me to toggle on or off the last line plotted:

val = app.VisibleOFFlastplotCheckBox.Value;
ax=app.UIAxes;
t = ax.Children(1); % Get last plot
switch val
case 1
t.Visible=’off’;
case 0
t.Visible=’on’;
end
Whilst this works, it doesn’t seem to remove the legend item, but instead Greys it out.
So to show this, the purple curve below is the one I want to remove / hide (note if remove it, I want the possibility of adding it back which is why Steven suggested the "visible" approach)

And here’s what happens once I set the visible property of the line to "off" – notice the legen item is still present

So how can I hide / temporarily remove the last legend item?

Thanks

How to limit input current of Asynchrous machine?

/ 2024-06-18 / Matlab

Hey, everyone,
I wana simulate a induction motor, as shown in the image. I chose DC voltage source(220V), Universal bridge(IGBT) to get a three-phase voltage source, and chose synchronous Machine SI Units block as induction motor. The control mode is V/F, and got ideal 1373 rpm speed, but sadly, the stator current was much larger than the rate current (0.79A), I dont konw why.
Now, I tried to limit the input current by Saturation block, but it can’t conncect to Universal bridge 🙁 .
Anyone helps? Looking forward.

Can you programmatically create a custom filter for Simulink model diffs?

/ 2024-06-18 / Matlab

We have some blocks in our models that we basically always want to ignore when doing a model diff, and I have made a filter for that. But as of right now, the only way to get that to other people working on the models is to export the filters, and then they manually import the filters. It would be ideal if the filters could be setup progromatically, either through the project file, or some other method to edit the definition, that way everyone would always have the same base filters.
Anyone know where the filters are defined for the user? Can I get into the xml file somewhere?We have some blocks in our models that we basically always want to ignore when doing a model diff, and I have made a filter for that.
