Good evening
I have a matrix H which has the dimensions 16×16×10
I want to multiply H by a vector of ones x to result in having a vector of 16×10
How can I accomplish this?
Kind regards,

How are you expecting to lose a dimension by multiplying by a vector? What is the operation here?
Generally, with array expansion or broadcasting (python) you might expect to gain a dimension when multiplying by a vector rather than lose one.

[m,n,p]=size(H); % size of H =>16X16X10 , size of x => 1X16
aa=reshape(a,[m n*p]);
Result=reshape(x*aa,n,p); % size of Result => 16X10
