Matrix Multiplication in DAX

Hello everyone,
I really need your help.
I have two matrices and I want to multiply the matrices with each other.
I found a way to do it, as you can see in the picture:

but the matrix written in the test file only works on physical tables.
The matrices on my real data are virtual tables (My Data File):

and I need your help to find a way to multiply these matrices with each other.
Can anyone help me?
