That would yield a 10 x 10
The number of columns of the 1st matrix must equal the number of rows of the 2nd matrix.
And the result will have the same number of rows as the 1st matrix, and the same number of columns as the 2nd matrix.
Okay I got the definitions of your 3 matrices.
What is M[2,3]?
You want the dimensions of A1 x A2 x A3?
]]>A1 = 5x10
A2 = 10x3
A3 = 3x10
Would M[2,3] be equal to (10*3*10) or (10*3)?
