How can I add my own electrical supply data to the PEMElectrolysisSystem simulation?
I have on my workspace my own data of voltage and current that I would like to use as an Electrical Supply for the Electrolyzer. The data is type: double, size: 934906 x 1. I would like to understand how do I use my data and connect it in the Simulink model? I have tried using the ‘From Workspace’ block after adjusting my data to be in ‘timeseries’ class, but with no success. I would like to understand what class should my data be in, what block to use and where to connect my inputed data?

Converting Mathcad to Matlab
I have a book with some good radar equations in it. However, everything is in Mathcad – I use Matlab. I’ve been converting everything I use from Mathcad to Matlab. I’ve run into one I’m not sure how to convert.
Mathcad has a function called root. The equation I’m interested in converting is:
root(f1(u) – sqrt(0.5), u, 0.3, 0.7
As I understand it, ‘root’ returns the value of u to make the function f1 equal to zero. With 0.3 and 0.7 being specified, root finds u on this interval.
How do I accomplish the same thing using Matlab?
Thanks,

How can I continue a Simscape simulation after altering some blockparameters?
Hi,
I am using fast restart to run Simscape model. I have the initial states of the blocks as block parameters defined in the matlab workspace. I would like to change certain parameters (say change the pressure at one point to a higher value) to simulate an external event and continue the simulation without altering rest of the system state. Preferably using fast restart. What is the cleanest way to achieve this? Is is possible to reinitialize just a single block using setBlockParameter() function and contine the simulation?
I have tried:
Run simulation -> save state -> change blockparameters (structs defined in workspace) -> load state ->run.
This doesnt work as I get the following error:
‘Simulink cannot load the initial operating point because the model, ‘model..’, was changed after the operating point was saved. Run the simulation again and resave the operating point.’
I already verified that the struct that is being changed is of the same dimensions and datatype after, just their numerical values are changed.Hi,

As there are so many listeners all over the place, simply querying or changing some object property frequently has unexpected side effects, making debugging very painful. Is there a simple way to get a list of all the listeners for a given property? E.g. something to the extent of getlisteners(obj.myProperty)? This would really help in figuring out what on earth the code is actually doing…

How can insert a ‘bodeplot’ in an axes object of AppDesigner.

Now, I am migrating the application to Matlab 2020a with AppDesigner, and I have found a problem with the calls to the Matlab function ‘bodeplot’.
"Error using DynamicSystem/bodeplot (line 113)

Dependency management & package manager like pip in ML
Hi all,
Matlab is officially still lacking a proper package manager like npm or pip. I do not understand how people structure projects with dependencies. I understand, there are
ML projects
ML toolboxes
several mpm versions
Toolboxes have a version number attached, projects have not. Both can be shared as a package. Projects can reference other projects, but that 1. requires the same folder structure on every developer PC and 2. requires that the correct version is checked out from the VCS (which is GIT in our case). There’s no way to define "project abc@v1.2.0" as a dependency. Just folders/prj files.
How do you do complex app developments? Like a frontent GUI app that needs several self-created toolboxes and projects? The only way is to use GIT (submodules in worst case) to do dependency managment, and that’s definitely a red flag.
Then, there’s Matlab’s mpm matlab-dockerfile/MPM.md at main · mathworks-ref-arch/matlab-dockerfile (github.com) but that’s meant to be used to install different product versions and addons, and there’s a third party mpm mobeets/mpm: Simple Matlab package management inspired by pip (github.com) which seems to be interesting, but there’s no direct support from Mathworks.
Then, it seems like there’s another mpm built-in in ML 2022b that mentions a Matlab -packages flag which is very interesting:
mpm
There’s no information about that. Starting ML with -packages reveals more:
Which seems to support different versions. But there’s no documentation anywhere, and it’s a built-in function © 2022.
What does that mean? Will there be a Mathworks’ supported package manager? What exactly is a package by the way in ML? So far, packages were a synonym to namespaces, using the +package folders. How does that work together with ML projects?
I’m in the process of re-structuring code due to a migration from Bitbucket to Gitlab and I’m at a point where a proper dependency management must take place, and that must work in CI/CD, too.
Would be very happy to hear your thoughts.
Thanks,
JanHi all,
Matlab is officially still lacking a proper package manager like npm or pip. I do not understand how people structure projects with dependencies. I understand, there are
ML projects
ML toolboxes
several mpm versions
Toolboxes have a version number attached, projects have not. Both can be shared as a package. Projects can reference other projects, but that 1. requires the same folder structure on every developer PC and 2. requires that the correct version is checked out from the VCS (which is GIT in our case). There’s no way to define "project abc@v1.2.0" as a dependency. Just folders/prj files.

Change marker colour of pzplot
Hello everyone
I’m trying to change the marker color in the pzplot graph. I’m using version 2024b.
Apparently, in this version, a new object(?) called "PZPlot Properties" was introduced, which is great.
Using this new object, I can easily change the size and line thickness of all markers. But I can also only change the colour of all markers. I’d like to change the colours of the markers for the poles and zeros separately.
I tried using the "findobj" method and found, that the PZPlot apparently consists of two Scatter-Plots called "PZPoleScatter" and "PZZeroScatter", and I tried changing the color of the markers in those Scatter plots, but this does not seem to have an effect on the markers.
When I change the colour of the markers using the PZPlot properties Object, I see the color definition of the markers in both scatter plots change, and I can also see that the colours change if I directly access the properties and change the colour, but the plot isn’t drawn with those correct colors.
I tried using refresh after changing the values, but that doesn’t have any effect either.
See my code below:
s = tf(‘s’);
f = (1 + 1/s)
pzp = pzplot(f);
% See https://ch.mathworks.com/help/ident/ref/controllib.chart.pzplot-properties.html for new PZPlot-properties object
pzp.Responses.MarkerSize = 10;
pzp.Responses.LineWidth = 2;
%pzp.Responses.Color = ‘green’; % Changes colour of all markers
oPole = findobj(gca, ‘Tag’, ‘PZPoleScatter’);
oPole.MarkerEdgeColor = ‘red’;
oZero = findobj(gca, ‘Tag’, ‘PZZeroScatter’);
oZero.MarkerEdgeColor = ‘blue’;
rsp = findobj(gca, ‘Tag’, ‘PZPoleScatter’); % read object again to see if properties got changed correctly
I also found the following two topics, but they do not work anymore as there is no "Line" child in the PZPlot object.
