A common customization is to check if the inverse of the source matrix does not exist. This happens when the determinant of the source matrix is 0. The determinant is 0 when any element on the ...

If the determinant of a matrix is 0, then the matrix doesn't have an inverse. Because the determinant is -115.0 the matrix does have an inverse which the demo computes as: 0.1565 0.2348 0.2696 -0.3391 ...
