An efficient way to round decimal numbers up to the n-decimal in a cell array
eIs there an efficient way to round decimal numbers up to the n-decimal in a cell array?
In the following example, I would like to round the decimal numbers up to n=2, i.e. to the second decimal:
a = [
{[ 0.235089379668094 0]}
{[0.0793405810870535 0]}
{[ 0.142843392632868 0]}
{[ 0.639081029130393 0]}
{[ 0.970756532033504 0]}
{[ 1 0]}]
My desired output would be the following one:
a = [
{[0.24 0]}
{[0.08 0]}
{[0.14 0]}
{[0.64 0]}
{[0.97 0]}

Generation of SPWM waveform with dead-time for a new circuit topology inverter using MATLAB
Hello MathWorks Community,
I am currently working on a project where I need to generate a Sinusoidal Pulse Width Modulation (SPWM) waveform that includes dead-time for a new inverter circuit topology. I intend to use MATLAB for this task, but I am having difficulty figuring out how to get started.
An important aspect of this problem is that the reference signal (sinusoidal) I want to use is not the typical M*sin(ωt), but rather (1/(2-M*sin(ωt))). I would appreciate if you could consider this when giving me advice on how to proceed.
Does MATLAB have built-in functions that can be used for generating such SPWM waveforms? If so, what are these functions and how can they be utilized effectively? Also, are there any recommended methods for handling the dead-time and the peculiar reference waveform in this context?
If you have examples or tutorials that are closely related to this problem, I would be very grateful if you could share them.
Thank you in advance for your support.Hello MathWorks Community,

Bayesian Optimization in real-time with Simulink and Code Generation
For a particular application, I need to implement Bayesian Optimization so to continuously run in a Simulink model. The simulink model is a control algorithm, which has to be translated into C code, and run on an ECU. The Bayesian Optimization should update the controller parameters (which are the parameters to be optimized) based on a certain cost function, which is directly measured from some sensors available to the ECU. So in practice my cost function should "wait" for a flag "experiment completed" coming from the simulink model; after the flag is generated, the cost function is evaluated based on the data.
More in details, the algorithm idea is something like this:
Perform the experiment by using a certain set of parameters.
After the experiment is done, the cost function for that set of parameters can be evaluated.
Run an iteration of bayesopt() and update the GP model, etc. A new set of parameters is selected through acquisition function.
The experiment is then performed again, and the new cost function is evaluated, and so on…
Now, I know that I can’t directly use bayesopt() in code generation.

dealing with and / (windows vs. unix) for path definition.

Simple question, let’s say I’m using mac osx and some colleagues use windows… and I have to share a matlab script. Problem, this script needs to look in folder to load data files or print figures:
load ./data/data.mat
plot(data(:,1),data(:,2))
print -dpdf ./graph/figure.pdf
this is how it is written on unix system, but on windows I have to replace all the / by
load .datadata.mat
…
Is there a way to deal with that or the only way to make it works on both systems is to add a conditional statement like

Appdesigner: Remove Simulink dependency
Hi everybody,
I have accidentaly added a Simulink component to my app and now I cannot compile it anymore.
I have the MATLAB compiler but not the Simulink compiler, to overcome the problem I have removed the simulink component but the dependency is still there, hence the appdesigner does not allow me to compile the app.
Is there any trick that I can use to fix this problem?
Best regards,

Anova-N output question
Hello community!
The closest prompt I could find that is similar to this would be: https://www.mathworks.com/matlabcentral/answers/1876737-anova-n-outputs-as-not-full-rank-returns-nan-p-value?s_tid=sug_su , but the reason their’s showed NaN was there was not enough values. For mine I have 5.4 thousand entries, so I’m not sure that is the problem.
To reduce clutter of the code, I am going to attach the .mat files and the one-line of code.
pTHalf = anovan(stats(:,1), {Patho CellLine MW},’model’,’interaction’,’varnames’, …
{‘Pathology’,’Cell Line’,’Molecular Weights’});
I ensured the data is of the same types allowed within the format of the Anova-n overview page. The only thing that I could think of was that there are more than two groups within the Cell Line and Molecular Weights groupings, but the only one that worked was the molecular weights, so I also doubt that is the reason.
This is the output below. Why do I have missing sections associated with a ‘not full rank’. I do not see anything on the anova-N page that discusses this.
Thanks community!

Bear tool box and input excel
While I am using the Bear toolbox to run time varying parameter model. I am bit confused how can I make my excel sheet to be recognized by the bear app. I import my own excel sheet that I used to collect data and every time I click a run button it says something like exo mean priors not found or something similar to this. I assume there is an excel sheet format that I am supposed to use in bear toolbox but I cannot really find it anywhere. Can anyone help me out?

How can I update base body transformation matrix during visualization using ‘show’ function?
To visualize the rigidbody tree model from urdf file, the ‘show’ function can be used. However, it supports to set the base body position (x,y,z) and yaw angle, only… I want to arbitrary set the base body position and orientation.
For a internal function in the robotics toolbox, there is a little comment to use 6-DOF xyz & roll, ptich, yaw, thereby obtaining whole base body transformation matrix. But, the strict support does not provide or activate them.
How can I set arbitrary base body transformation matrix of rigidbody tree? I have to simulate the base body trasnform almost real-time, therefore I don’t want to add and remove body during simulation.To visualize the rigidbody tree model from urdf file, the ‘show’ function can be used.

How should I structure the neural net based on my given input and output training data
I am trying to design a feedforward network that trains on a 4×5 matrix (5 samples of 4 separate inputs into the neural network) and its outputs are represented by a 4x5x1000 matrix (5 samples of 4 outputs where each component of the 4×1 output vector has 1000 points). This neural net is used to determine an optimal trajectory for a given terminal condition from a set of the same initial conditions . The code for this project will be placed below:
%% Neural Net Training Process
% Initial State
x1 = [0;0]; % Initial Positions
x2 = [1;1]; % Initial Velocities
xo = [x1;x2]; % 4×1 Initial State Vector
% Parsing Training Input Data
x_input = [xf1,xf2,xf4,xf5,xf6]; % 4×5 Terminal State Vector (each xf (4×1) represents a different terminal condition)
% Parsing Training Output Data
x_output = [];
for i=1:4
x_output(i,1,:) = x1(:,i);
x_output(i,2,:) = x2(:,i);
x_output(i,3,:) = x4(:,i);
x_output(i,4,:) = x5(:,i);
x_output(i,5,:) = x6(:,i);
end % 4x5x1000 Terminal State Matrix
