For example, is the upper limit of i in the for loop automatically generated based on factors such as the size of the data or something else?I would like to interrupt the process of generating data into smaller segments as per my request, but I don’t know how to handle these data or intermediate quantities because I am concerned that interrupting this process directly may lead to uncontrollable issues such as data leakage or data coverage。For example, is the upper limit of i in the for loop automatically generated based on factors such as the size of the data or something else?I would like to interrupt the process of generating data into smaller segments as per my request, but I don’t know how to handle these data or intermediate quantities because I am concerned that interrupting this process directly may lead to uncontrollable issues such as data leakage or data coverage。 For example, is the upper limit of i in the for loop automatically generated based on factors such as the size of the data or something else?I would like to interrupt the process of generating data into smaller segments as per my request, but I don’t know how to handle these data or intermediate quantities because I am concerned that interrupting this process directly may lead to uncontrollable issues such as data leakage or data coverage。 simulink, signal MATLAB Answers — New Questions

Greetings,

Using MATLAB/Simulink 2019b. The interface while modifying my model can get really slow and laggy. Even just simply clicking, dragging, and resizing. Scrolling the wheel to zoom in/zoom out, along with attaching connections.
Is there anything I can do to increase the performance. My laptop isn’t the newest, but it’s also not that old. I use 64b windows 10, 64b MATLAB. I’m at 10/16 GB of memory used with MATLAB taking 1.5GB and a constant 15-25% CPU.

I have two models open, and some MATLAB code. Really would appreciate any advice on increasing the general UI performance.

Edit: Restarted MATLAB. without a model open it idles with 0% CPU. When I open the model it "idles" at 10+% CPU. Just having the model open and not interacting with it.Greetings,

I’m trying to solve a basic ODE (transient energy balance in a stirred tank). I can easily solve my equation using this code below (simplified).
However, I need to automate a parametric sweep so I can vary things like the size of the tank or the heater duty etc and plot all the curves on a single graph. I’ve looked around this forum and the support docs but can’t really find a solution. I would like to stick to the symbolic toolbox if possible, since it’s much neater and elegant than definiting separate functions the old way, but if that’s the only solution, then happy to do that.
Is there a simple way to do this? I’ve attempted to use a for loop but I get index errors pop up.
I haven’t used matlab since undergrad (10 years ago), so am a bit rusty.
syms T(t)
ode = m_w * Cp_w * (diff(T,t) – T_ref) == (m_in * Cp_w * (T_in – T_ref)) – (m_out * Cp_w * (T(t) – T_ref)) + Q_heater – (R_tot * (T(t) – T_amb) * A_ins);
cond = T(0) == T_amb;
TSol(t) = dsolve(ode,cond);
fplot(TSol,[0 3600]);I’m trying to solve a basic ODE (transient energy balance in a stirred tank). I can easily solve my equation using this code below (simplified).

Hi all,
I have been building a web app through App Designer on MATLAB R2023b and tried to use the custom fonts "Kanit" and "Montgomery" for my UI.
Although the custom fonts show in the app on my developer desktop after copying them to "<matlabroot>sysjavajrewin64jrelibfonts", the app shows a fallback font on a different computer through my LAN.
My question is how do I ensure that the web app also use these custom fonts on computers that do not have them installed?
I have attempted to embed an HTML block in the app UI to access the Google Font API with the following code,
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=kanit"><link rel="stylesheet" href="https://fonts.googleapis.com/css?family=montgomery">
but my Chrome browser’s console returned the following error message "Refused to load the stylesheet ‘https://fonts.googleapis.com/css?family=kanit’ because it violates the following Content Security Policy directive: "style-src ‘self’ ‘unsafe-inline’". Note that ‘style-src-elem’ was not explicitly set, so ‘style-src’ is used as a fallback."
All help would be greatly appreciated – thank you!Hi all,

Hello Matlab App Developer wizards.

Had a quick question. So I have this drop-down in a matlab app that calls a variable "Yield_raw(:,2)" to create a list. I want to know the index (i.e. row and column) of "Yield_raw" when this is selected. Any pointers? My code looks as follows:
Creates drop down
function ImportYieldFileButtonPushed(app, event)
[Yield_import, Yield_location] = uigetfile(‘*.xlsx’, ‘Select Yield File’, ‘\chlm2efs01US_Share’);
Yield_raw = readtable([Yield_location, Yield_import]);
Yield_raw = table2cell(Yield_raw(:,[1,3:13]));
if exist(‘Yield_raw’,’var’)
app.Lamp_Yield.Color =’g’;
end
app.ProcessDropDown.Items = Yield_raw(:,2);

Selected drop down
function ProcessDropDownClicked(app, event)
% item = event.InteractionInformation.Item;
%%HOW DO I GET THE INDEX IN YIELD_RAW FOR THE VALUE I SELECTED IN THE DROP DOWN []
