How to use reshape
显示 更早的评论
Hi, I have a matrix m (x, y, z) with a size of 12x6x5. I would like to reshape the matrix having other z-values given in f (5x1 vector). I have written the reshape command like this: g=reshape(f, [m],3) This is the error message: Error using reshape. Size arguments must be integer scalars. I don't understand the error. Thanks for your help!

I don't understand what you are trying to do. Reshape simply changes the shape of one matrix as shown in
doc reshape
What you are wanting to do seems more complicated. Can you give an example of what you are trying to do and what result you are expecting from what inputs.

What is [m] ?

It appears that ‘m’ is the (12x6x5) original matrix.
We need to know the desired result.

Assuming you want to change all 3rd dimension values to the vector f, this code should do what you want.
for n=1:length(f)
g(:,:,n)=f(n);
end
You can remove the loop by using repmat on the result of reshape(f,[1 1 5]) or permute(f,[2 3 1]).
