The matrix multiplication algorithm that results from the definition requires, in the worst case, multiplications and () additions of scalars to compute the product of two square n×n matrices. Then you'll be able to write: It is multiples of the identity matrix that most act like scalars, both when multiplying with other matrices, and when using them to linearly transform vectors.

There Are Two Types Of Multiplication For Matrices:

You just take a regular number (called a scalar) and multiply it on every entry in the matrix. For the multiplication of two compatible matrices below are some general steps to be followed. We need to ensure that columns of the first array are.
