To use the default operation (multiplication), the syntax is: =SUMPRODUCT(array1, [array2], [array3], ...) Arguments Array1 is the first range or array to be multiplied. Array2 is the second range or array to be multiplied. Array2 and all subsequent arrays are optional. Return value...
array2 Required The second array that you want to multiply. Return Parameter: A matrix of number arrays. Basics of Matrix Multiplication We have two matrices, A and B., where A is an m by n matrix and B is an n by p matrix. The product of these two matrices, C = AB; can be...
In arithmetic we are used to:3× 5 = 5 × 3 (The Commutative Law of Multiplication)But this is not generally true for matrices (matrix multiplication is not commutative):AB ≠ BAWhen we change the order of multiplication, the answer is (usually) different....
