numpy.linalg:det
source: build-install/usr/lib/python3.14/site-packages/numpy/linalg/_linalg.py :2355
Signature
def det ( a ) Summary
Compute the determinant of an array.
Parameters
a: (..., M, M) array_likeInput array to compute determinants for.
Returns
det: (...) array_likeDeterminant of
a.
Notes
Broadcasting rules apply, see the numpy.linalg documentation for details.
The determinant is computed via LU factorization using the LAPACK routine z/dgetrf.
Examples
The determinant of a 2-D array [[a, b], [c, d]] is ad - bc:import numpy as np a = np.array([[1, 2], [3, 4]])✓
np.linalg.det(a)
✗a = np.array([ [[1, 2], [3, 4]], [[1, 2], [2, 1]], [[1, 3], [3, 1]] ]) a.shape np.linalg.det(a)✓
