qdet

In linear algebra and statistics, the pseudo-determinant[1] is the product of all non-zero eigenvalues of a square matrix. It coincides with the regular determinant when the matrix is non-singular.

qdet

Computes the quasi-determinant of the square matrix x. x can also be a singular matrix.

Usage:

qdet(x)

Result:

The quasi-determinant of x.

Return Type:

a scalar
