Hello,
I have some 649x1 double data saved in "Fidelity_result.mat" file from a matlab code. I want to plot these data as y axis and x axis should be entries from 1 to length of the entries in "Fidelity_result.mat" file. The matlab code shows no error but the figure displayed at the end is blank.
folder = 'C:\Users\Laborbenutzer\Desktop\Tomography Test Akriti';
y=load("Fidelity_result.mat");
y_fidelity=y.Fidelity_result;
x_fidelity=(1:1:size(y_fidelity,1)).';
plot(x_fidelity,y_fidelity)

Please upload your MAT file by clicking the paperclip button.

The plot is not blank here, see below.
"The matlab code shows no error but the figure displayed at the end is blank."
Could you share the screenshot of the code ran along with the screenshot of the figure generated?
y=load("Fidelity_result.mat");
y_fidelity=y.Fidelity_result;
x_fidelity=(1:1:size(y_fidelity,1)).';
plot(x_fidelity,y_fidelity)
Also, if you want to plot against indices, you can plot it directly -
figure
plot(y_fidelity)

I would do it like this:
load (websave('Fidelity_result.mat', 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1618953/Fidelity_result.mat'))
x = 1:numel(Fidelity_result);
plot(x, Fidelity_result)
