hi

i want to save multiple vectors in a .mat file in order to have a (15*19) array- i mean i want to have many vectors within for loop how can i do that this is the code i used:

hhist=hist(h(:), numberofbins);
shist=hist(s(:), numberofbins);
vhist=hist(v(:), numberofbins);
vector = [hhist, shist, vhist, status];
save(savefile, 'vector');

thank u all

What in that code do you expect to be 15 by 19? What does the 15 represent, and what does the 19 represent? Where is the for loop?

In order to save multiple vectors into a .mat file without having the variables write over each other, each of the variables needs to have a different name. The FAQ above describes how to work with variable names whose names themselves change during a loop.

Have you considered the alternatives, such as creating a single variable that holds all of the results, and saving that one variable after the loop?
