i have 3D data that will be squeezed to 2D data matrix. the data is 116x150x45 where after the squeeze, i want to take out sample 1-25 only,
thus, Y should have 25 for Y(1) until Y(25), but i only got Y that will extract and replace after squeezing. anyone can help?
for a = 1:25
Y=squeeze(fmridata(:,:,a)); % for healthy patients from 1-25
end

It will still be stored in 3d yes. But how it is stored in a variable doesn't really matter. It's what you do with it from there that matters.

Something like this is probably what you're looking for, although it makes it more difficult to compare the same pixel over all patients.
Y=cell(1,25);
for a = 1:25
Y{a}=squeeze(fmridata(:,:,a)); % for healthy patients from 1-25
end

My code will result in a cell array with 25 elements, where each cell contains a matrix of 116x150. This avoids numbered variables, which are a bad idea in general.
As indicated by others: The squeeze is not needed, and a 3D array is probably a better idea, depending on what you want to do next with this array.
