Numerical Modeling: Topic 1.4 - The determinant

Clarification: At 0:30 I should have said that a small determinant can be an indication of an ill-conditioned system of equations. The condition number (not covered in this video) can give a better indication of whether the system of equations is ill-conditioned.

Determinant close to zero does not mean ill conditioned system of equations.
