Suppose I have the following code
U_range=20:25;
for i=1:6
U=U_range(i);
Result=U^2;
save('C:\Users\KKB\Documents\U=20\Result.mat','Result'); % Only for U=20,Modification required here ????
end
I want to save All Result (here six), in the specified path i.e.,C:\Users\KKB\Documents, but the folder name where the six Result will be saved are respectively U=20,U=21,U=22,U=23,U=24 and U=25. It should be noted that six empty folder having the above mentioned name are already created in the specified path. Only the Result need to be save in those respective folder. How to do that?

You can use num2str on your loop iterator to build up the folder name. For example:
for ii = 1:3
a = rand(ii);
fdr = ['/Users/davidbarry/Documents/MATLAB/', 'U=', num2str(ii)];
if ~exist(fdr, 'dir')
mkdir(fdr);
end
save([fdr, '/Result.mat'], 'a');
end
By the way, I would avoid having equals symbol in the folder or file name but that's up to you.
