Basic Maths:Just for matrix multiplication, you can
The number of columns in the first matrix must be equal to the number of rows in the second matrix.
But for dot multiplication, how can you do that?
Suppose m1(1,1)*m2(1,1)..so on
Not have sufficient elements to pair each other. For dot operation both must have same sizes.
So the answer is No.
