How do we determine whether a matrix has an inverse?

Web1. you write both matrix and the identity matrix side by side. So what you see is like a 3x6 matrix (first three columns are the matrix and second 3 columns are the identity) 2.Now you use simple operations on them to get the identity matrix on your left 3 columns, if you have done this, then the right 3 columns are now the inverse of your matrix. WebThe matrix must be square (same number of rows and columns). The determinant of the matrix must not be zero. This is instead of the real number not being zero to have an inverse, the determinant must not be zero to have an inverse.
