I have multiple files (sub1, sub2, sub3......subn) in matlab workspace and wants to apply a loop to extract the features. There is error in the code. Kindly guide me to fix this issue. My code is as follow:
s=43;
theta=[ ];
% numsubjects = length(sub);
for sub_i=1:s
subject = sub(str(sub_i));
theta1=mean(subject(3:7,26,:));
theta=[theta,theta1];
end

Don't do that. Do not allow them to be created into different variables in the first place, and then you will not have to hack to dynamically create variable names.

Thanks for the feedback. I already have all these files (sub1,sub2....sub43) in matlab workspace. Now I want to extract features from these files. I need to apply loop to extract all the features.

Then you need to change how you get them in your workspace. You're forcing yourself to write terrible code. Why would you do that for no good reason?
