6.47.5  Determinant of a sparse matrix: det_minor

The det_minor command finds the determinant of a matrix by expanding the determinant using Laplace’s algorithm.

• det_minor takes one argument:
  A, a matrix.
• det_minor(A) returns the determinant of the matrix A.

Examples.

• Input:
  det_minor([[1,2],[3,4]])
  Output:

  −2

• Input:
  det_minor(idn(3))
  Output:

  1
