How to Multiply Matrices. A Matrix is an array of numbers: (This one has 2 Rows and 3 Columns) To multiply a matrix by a single number is easy: These are the calculations: We call the number ("2" in this case) a scalar, so this is called "scalar multiplication". Multiplying a Matrix by Another Matrix.
On this page you can see many examples of matrix multiplication. You can re-load this page as many times as you like and get a new set of numbers and matrices each time. You can also choose different size matrices (at the bottom of the page).
17 wrz 2022 · Multiplication of Two Matrices. Let A be an m × n matrix and let B be an n × p matrix of the form B = [B1⋯Bp] where B1,..., Bp are the n × 1 columns of B. Then the m × p matrix AB is defined as follows: AB = A[B1⋯Bp] = [(AB)1⋯(AB)p] where (AB)k is an m × 1 matrix or column vector which gives the kth column of AB.
