That word is in quotes because matrices technically cannot be divided. Instead, we multiply one matrix by the inverse of another matrix. These calculations are commonly used to solve systems of linear equations.

Find the determinant of matrix [B] by calculating ad-bc , where [ a b ] is the top row and [ c d ] is the bottom row. Did this summary help you? Yes No. Log in Social login does not work in incognito and private browsers.

Tips and Warnings. Related Articles. Article Summary. Part 1. Understand matrix "division. Dividing a matrix by another matrix is an undefined function. Since these two equations would be equivalent for scalar quantities, this "feels" like matrix division, but it's important to use the correct terminology. You may need to solve both to find all possible solutions. Confirm the "divisor matrix" is square.

To take the inverse of a matrix, it must be a square matrix, with the same number of rows and columns. If the matrix you're planning to inverse is non-square, there is no unique solution to the problem. A matrix that has an inverse is called "invertible" or "non-singular.

Check that the two matrices can be multiplied together. To multiply two matrices together, the number of columns in the first matrix must equal the number of rows in the second matrix. For example, if [A] is a 4 x 3 matrix 4 rows, 3 columns and [B] is a 2 x 2 matrix 2 rows, 2 columns , there is no solution. Note that the inverse [B] -1 always has the same number of rows and columns as the original matrix [B].

There's no need to calculate the inverse to complete this step. In our example problem, both matrices are 2 x 2s, so they can be multiplied in either order.
