Webread Query Not Working
I am looking to query a forum style page (this forum, actually), but cannot seem to the the queries working as desired.
My goal is to essentially get the most viewed questions about Simulink (as woud be done via this page: https://www.mathworks.com/matlabcentral/answers/?product_base_code%5B%5D=Simulink&sort=views+desc)
However, when I try this via webread, the page I get is just the base Answers page, and it isn’t giving me Simulink, nor the sorting.
I am using the following (where indexed will be looped for multiple pages):
url = ‘https://www.mathworks.com/matlabcentral/answers/’;
data = webread(url,’page’, index,’product_base_code%5B%5D’,’Simulink’,’sort’,’views+desc’);
Any advice/help would be greatly appreciated.

How to evaluate a fistree designed with the new addition to the app?
Hello,
How can I import and evaluate a fistree designed in the new addition of the FuzzyLogic Toolbox app?
It is saved as .mat file instead of .fis.
Readfis and load do not seem to work to import it to my script. I want to give inputs via evalfis, but it does not seem to work with the .mat file. It seems that it is not recognized as fistree.
Many thanks in advanceHello,

Find the ratio or difference spectra as time progresses
Hi, I have a number of spectra that has been collected over a certain number of hours. How do I compute the difference spectra or ratio spectra over that time period? So say spectrum 1 is rationed with spectrum 2, spectrum 3 rationed with spectrum 2 etc. can same be done with difference spectrum as well? Any algorithm to do this?

How to split my EMG signal into individual cycles?
Hi I have recorded an emg signal of 5 different muscles on someone performing manual wheelchair propulsion.
Sensor 1 = biceps
Sensor 2 = triceps
Sensor 3 = Anterioir Deltoid
Sensor 4 = Posterior Deltoid
Sensor 5 = Upper Trapezius
Each sensor also records the acceleration in the x, y and z directions.
I want to split the emg signal into seperate propulsion cycles (when the hand pushes and releases to when the hand hits the push rim again.) so that I can average each cycle, as well as convert time (s) to percentage of cycle.
I know there were 13-14 cycles during the recording as i videoed the subject while gathering data.
I have only looked at the bicep data as shown below and was wondeing if there is a way to do this with the information I have.
Please let me know if you need anymore information.

Compiled exe app doesn’t work on a function used within another function
So I have an app developed by MATLAB app designer. I have put my main backend code in a function and call that function on button press.
Here is my problem: While running in app designer everything is fine, but when I compile it as a stand-alone exe file and install it, the code doesn’t work properly. So I used messages in different parts of code to debug it and I find out that it stops as soon as it reaches first function used in the main function. Here is a demonstration of my main code, note that this is the main function called by app designer:
function maincode
x = 1;
y = 2;
z = secondfunction(x,y);
end
and my secondfunction is saved in another .m file (which I include in additional files before packaging)
function [sum] = maincode(first,second)
sum = first + second;

How to plot one curve and change color according to value
The tricky thing is that I get an attribute with the values and would like to have this part in the plot in a different color:
x = linspace(0,10);
y = sin(3*x).*exp(0.5*x);
c = find(y > 25);
m(length(x)) = 0;
m(c) = 1;
figure;
plot(x, y, ‘b’)
Where m becomes 1 the color should be red, else blue.

m(c) = 1;
figure;
plot(x, y, ‘b’)
Where m becomes 1 the color should be red, else blue.
Can someone find the easiest way to do this? The tricky thing is that I get an attribute with the values and would like to have this part in the plot in a different color:
x = linspace(0,10);
y = sin(3*x).*exp(0.5*x);
c = find(y > 25);
m(length(x)) = 0;
m(c) = 1;
figure;
plot(x, y, ‘b’)
Where m becomes 1 the color should be red, else blue.

Source code for solving second order PDE using PINN
Hi
Can someone share the matlab source code for solving second order ODE of the type as below?
I could build a sample code using : https://uk.mathworks.com/help/deeplearning/ug/solve-partial-differential-equations-with-lbfgs-method-and-deep-learning.html#responsive_offcanvas
But, I am not sure how to input the IC of the form d/dx() in the code.
All help will be appreciated.

Nondimensionalizing Length and Temp data from 2-D Ansys Transient thermal in Matlab
I have a text file that has dimensionalized data from Ansys (in micron and Kelvin). The first column is length and the second column is temperature. I am trying to nondimensionalize these data points and then put them in a graph where the x-axis represents nondimensionalized length and the y-axis represends nondimensionalized temperature.
xs = 100µm
Tf = 500K
Ti = 300K
