Making a simple example, where I load a .mat file to append to a variable. How do I then save the .mat file again after the appending?
current = [1 2 3];
new_current = [4 7];
volt = [7 5 4];
save('data.mat','current','volt');
data = load('data.mat');
data.current = [data.current new_current];
save .matfile?!?!!

save(FILENAME, ..., '-append') adds new variables to an existing file.
in your case,
save('data.mat','new_current','-append');

Hi.
Thanks for the answer but that is not what I want. I want to replace data.current with the new data.current I have made from:
data.current = [data.current new_current];

current = [1 2 3];
new_current = [4 7];
volt = [7 5 4];
save('data.mat','current','volt');
load('data.mat','current');
current = [current new_current];
save(file,'current','-append')
