5, Determinant:

Determinant is another mathematical tool we need to find out the X-1 that we need to calculate T.

You can always test if a matrix has an inverse, that's when the determinant is not zero.

det(T) = not equal zero

In the computer world we don't have infinite number to work with, not resolution enough, we get rounding errors. So if the determinant have a very small value it's the same as it probably will not have an inverse.

More information about determinant:
