WebApr 10, 2024 · As you can see the result for the determinant is much nicer, the one for the inverse seems to be as ugly than what you got in P8. Using 0.8 forces the symbolics in some sort of numeric/floating point mode (unfortunately). If possible its always worth a try to change float numbers to fractions with integers. WebInverse matrix using determinants Inverse matrix using determinants Apart from the Gaussian elimination, there is an alternative method to calculate the inverse matrix.
