When and why you can't invert a matrix.
Invertible Square Matrices and Determinants :
In order to determine if a matrix is an invertible square matrix, or a square matrix with an inverse, we can use determinants. The only matrix with a nonzero determinant is an invertible square matrix. An invertible square matrix represents a system of equations with a regular solution, and a non-invertible square matrix can represent a system of equations with no or infinite solutions.
This lesson will explain the concept of a "singular" matrix, and then show you how to quickly determine whether a 2x2 matrix is one
