Issues in Matrix multiplication

I have 100 6 by 6 matrices and 100 6 by 1 matrices and I want to multiply them. If I do X=A.*B it does not give me the correct solution. Does anyone know a way around this?

A somewhat less efficient solution (but which uses no 3rd party files) is,

A=rand(6,6,100);
B=rand(6,1,100);
C=sum( A.*reshape(B,1,6,[]) ,2);

Use mtimesx from the File Exchange

https://www.mathworks.com/matlabcentral/fileexchange/25977-mtimesx-fast-matrix-multiply-with-multi-dimensional-support

Example:

A=rand(6,6,100);
B=rand(6,1,100);
C=mtimesx(A,B);
