Hello all, I am trying to understand the meaning of following lines of code, but not getting it clearly.
file_x_train = strcat( file_px, num2str(ii),'_M',num2str(M), '_N',num2str(N),'_', num2str(SNRdB),'dB.mat' );
file_h_train = strcat( file_py, num2str(ii),'_M',num2str(M), '_N',num2str(N),'_', num2str(SNRdB),'dB.mat' );
m1=matfile( file_x_train,'writable',true );
m1.x_subtrain =data_SNR_train;
where, M = number of antennas, N = number of elements, SNRdB is a constant value say 10 decibels.
I understood that first and second line of code is related to filename for a MAT file.
But I am not getting what does third and fourth line of code indicates.
Any help in this regard will be highly appreciated.

Have you tried asking in MathWorks AI Chat Playground?
After providing it your code and description, I asked it to provide a comment for each line. Here are the results
% Create file names based on ii, M, N, and SNRdB
file_x_train = strcat( file_px, num2str(ii),'_M',num2str(M), '_N',num2str(N),'_', num2str(SNRdB),'dB.mat' );
file_h_train = strcat( file_py, num2str(ii),'_M',num2str(M), '_N',num2str(N),'_', num2str(SNRdB),'dB.mat' );
% Create a matfile object with write access using the file name from above
m1=matfile( file_x_train,'writable',true );
% Assign the variable data_SNR_train to the x_subtrain property of the matfile object
m1.x_subtrain = data_SNR_train;

Yes I should not have used load in my explanation. Thank you for the correction
