Hi

Kindly see my attached function. It is a callback function for a switch button
I have already converted both my grouping variables to categorical arrrays, still I am getting the message saying: "A grouping variable must be a vector."
I dont understand what more can be and should be done to the grouping variables.

value = app.Switch.Value;
if strcmpi(value, ‘on’)

weightpercentages = [app.Callingapp.Osmotisk_data.Weight_percent_best_salt_1 app.Callingapp.Osmotisk_data.Weight_percent_best_salt_2];

weightpercentages=categorical(weightpercentages);
Combo=categorical(app.Callingapp.Osmotisk_data.Combinations_of_salts);

[g,id1,id2]=findgroups(Combo, weightpercentages);
hold(app.UIAxes, ‘on’)

splitapply(@(x,y)scatter(app.UIAxes,x,y,’filled’),app.temperature,app.Callingapp.Total_water_activity,g)

legend(app.UIAxes,string(id1) + ", "+string(id2) ,’location’,’northwest’)

Hi everyone,
I am building a microgrid model in Simulink and I am hitting a brick wall during a specific weather transient event.
The Setup:
I have a 48V battery connected to a 200V DC Bus via a Bidirectional DC-DC Converter.
The DC Bus has a constant 1500W load, supported by Wind and Solar sources.
The converter uses cascaded PI controllers (Outer Voltage Loop, Inner Current Loop) to generate a PWM duty cycle via a Relational Operator and Triangle Wave (10 kHz).
The powergui is set to Discrete with a sample time of 1e-5.
The Problem:For the first 14.9 seconds, the Wind and Solar easily supply the load, and the excess power is pushed into the battery. The battery is charging (current is flowing in reverse).
At exactly t = 15.0 seconds, the wind and solar drop. The battery must instantly reverse current flow to discharge and support the 1500W load. At this exact millisecond, the simulation aborts. Scopes show a massive, instantaneous current spike as the current tries to reverse direction, causing the math solver to fail.
What I Have Already Tried:
Swapped to modern Discrete PID blocks with Anti-Windup (Clamping) to prevent integrator explosion.
Lowered the PI gains significantly to stop the controller from aggressively overreacting.
Disabled zero-crossing detection on the PID blocks.
Capped the maximum Duty Cycle at 0.85 to prevent infinite voltage commands.
I have attached a screenshot of my control loop and the scope showing the crash at 15.0s. Any advice or guidance on power electronics best practices in Simulink would be greatly appreciated!Hi everyone,

Hello everyone! I am new to MATLAB, and I am trying to use it to solve for some variables in a system of equations (this is for the node-voltage equations of a filter, but that isn’t fully relevant)
syms Va Vi Vhp Vlp Vbp R2 R3 R1 Rf R s C RH RB RL RF Vo

eqn0 = (( (Va-Vi)/R2) + ( (Va-Vbp)/R3) )== 0;
eqn1 = ( ((Va-Vlp)/R1) + ( (Va-Vhp)/Rf) )==0 ;
eqn2 = (-(Vhp/R) -(Vbp*s*C))==0;
eqn3 = (-(Vbp/R) – (Vlp*s*C))==0;
eqn4 = (-Vhp/RH -Vbp/RB -Vlp/RL – Vo/RF==0);

S = solve(eqn1, eqn2, eqn3, eqn0, eqn4)

Va, Vi, Vhp, Vlp, Vbp, and Vo are all "unknowns", while the rest are supposed to be treated as constants. Ideally, I want it to solve for H(s) = (Vo/Vi) .. Or really, I’d prefer to just be able to find out what every term rearranges to (i.e solving for Vbp, Vhp, Vlp, in terms of the other ones).
But when I run "solve", I get as follows.

Va: [2×1 sym]
Vbp: [2×1 sym]
Vhp: [2×1 sym]
Vi: [2×1 sym]
s: [2×1 sym]

Within these solutions are two (? why? is it not linear?.. Im not sure..) different expressions.

% For S.Vbp
ans =

-(Vlp*(RH – (-(RH*(4*RB^2*RF*Vlp + 4*RB^2*RL*Vo – RF*RH*RL*Vlp))/(RF*RL*Vlp))^(1/2)))/(2*RB)
-(Vlp*(RH + (-(RH*(4*RB^2*RF*Vlp + 4*RB^2*RL*Vo – RF*RH*RL*Vlp))/(RF*RL*Vlp))^(1/2)))/(2*RB)
%Besides the fact there’s *two* equations, this is what I want: just a big
%list of rearranged variables. But again: why two equations!

I am new to MATLAB and I do not really have a concept of the nature of linear equations (I haven’t taken linear algebra) besides "you need one for every variable you want to find", so I do not know where this issue may be coming from. Is it because all the other "variables" (constants) are being treated as variables and there aren’t enough equations? I’ve checked my equations with two friends and I am confident there’s nothing wrong with them.

Hi everyone,
I’m using the donutchart function (which returns a DonutChart object) and I’m looking for a supported way to disable chart interactions—specifically:
Data tips
The export interaction
For conventional plots (for example, line plots, scatter plots), I can usually disable interactions at the axes level. However, for donut charts I haven’t found an approach that reliably disables these interactions on the DonutChart object itself.
If anyone has a method (or knows whether this is currently not configurable for DonutChart), I’d really appreciate guidance.
Thanks a lot!

I have a large app with many test cases that I would like to be able run in parallel. However the uitest framework functions (type, press etc. ) all fail when run in parallel due to MATLAB:uiautomation:Driver:NoDisplay. Is there a way to set up the parpool to allow this?
I provide an example of this with a simple file selector app that uses uigetfile to select a file. If the file exists then the first line is written to a label in the app, otherwise an error message is written. The testing utilizes the uitest framework function "press" in both tests and it failes due to the error above when run in parallel. When run without parallel processes both tests pass without errors.
(I borrowed the original code base from the example provided in the answer linked below and modified it for this question)
https://www.mathworks.com/matlabcentral/answers/1989568-create-a-test-case-with-uitest-class-using-uigetfile-and-uiputfileI have a large app with many test cases that I would like to be able run in parallel. However the uitest framework functions (type, press etc. ) all fail when run in parallel due to MATLAB:uiautomation:Driver:NoDisplay. Is there a way to set up the parpool to allow this?

I would like to ask for your guidance regarding my use of the UCIe 2.0 Standard Package Signal Integrity Kit.
In the documentation, a script (run_plotVTF.m) for calculating the VTF is mentioned, as illustrated in the figure below. However, I was not able to locate this file after searching through the provided package.

I also have an additional question: is it possible to run the VTF calculation tool independently, without waiting for the coupled widebus simulation to be completed?
Based on my understanding, the VTF simulation itself is essentially a passive simulation.I would like to ask for your guidance regarding my use of the UCIe 2.0 Standard Package Signal Integrity Kit.
