I have a matrix which size is ,

A= 256x256x31;

And another Matrix (4D) ;

B=2031616x64 [ 4D format is : ( 256x256x31)x64]

I need to multiply matrix A with Matrix B . For the above scenario it will be not possible as dimension is not matching.

Can any one help so that the size of B becomes the size of A so that I can multiply them .

I tried with the squeeze but nothinh is happening there. So, little but confused.

C = A .* reshape(B, size(A,1), size(A,2), size(A,3), []);

This assumes element-by-element multiplication, not matrix multiplication.

Your post said

B=2031616x64 [ 4D format is : ( 256x256x31)x64]

but your code says

B= ones(256, 256, 31, 'single');

which is only 2031616 elements not 2031616x64 elements.

Thank you . It is working Now.
