MATLAB: I want the code for this operation ⊗ on two vectors X and Y

matrix manipulation

Suppose that X and Y are two vectors of the same dimension: X=(x1,x2,···,xn)^T , Y=(y1,y2,···,yn)^T . Define an operation ⊗on X and Y as follows: X⊗Y=(x1×y1,x2×y2,···,xn×yn)^T.

example :

[0.2 0.6 0.5 0.9]^T ⊗ [1 1 1 0]^T = [0.2 0.6 0.5 0]^T

MATLAB: How to properly sum 3D matrixes

Use this function:

function M=sumnd(M,dim)
s=size(M);
M=permute(M,[setdiff(1:ndims(M),dim),dim]);
M=reshape(M,[],s(dim));
M=sum(M,2);
s(dim)=1;
M=reshape(M,s);
end

Code:

A=sumnd(M,3) ;
A = simplify(A) ;

Result:

[ x1*y1*(z1 + z2 + z3), x1*y2*(z1 + z2 + z3), x1*y3*(z1 + z2 + z3)]
[ x2*y1*(z1 + z2 + z3), x2*y2*(z1 + z2 + z3), x2*y3*(z1 + z2 + z3)]
[ x3*y1*(z1 + z2 + z3), x3*y2*(z1 + z2 + z3), x3*y3*(z1 + z2 + z3)]
