cmatrix.Matrix.det

Matrix.det()

Compute the associated determinant of the self matrix. To realize it, I decompose the self Matrix into from LU method and compute the associated determinant independantly. Teproduct of the Lower and Upper determinant give the det of the self matrix.

Returns

double
