Multiplication between two matrices with different number of rows

Dear all,

I have two matrices:

A=[42x5];

B=[32x1];

I want to multiply each row of B to each of A.

Kind help needed. Thank you.

@DV: please show us the size of the expected output array.

Expected to be: C=[42x32x5];

Thanks!

[Stephen23]

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

[Stephen23]

Testing:

A = rand(42,5);
B = rand(32,1);
C = permute(A,[1,3,2]) .* reshape(B,1,[]);
size(C)

ans = 1×3

42 32 5

Thank you sooooo much!
