Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.
\The dimensions of the matrix E are and the number of columns in the matrix E is 6.
The dimensions of the matrix F are and the number of the rows in the matrix F is 6.
The number of columns in the matrix E equals the number of rows in the matrix F.
\So, matrix product EF is possible.
\Its dimensions are .
The matrix product EF is defined and matrix EF dimensions are .
