Review Of Multiplying Matrices Since 2000 References

Review Of Multiplying Matrices Since 2000 References. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. For example, the following multiplication cannot be performed because the first matrix has 3 columns and the second matrix has 2 rows:
