Is_diagonal, diagonalize property is_indefinite #Ī positive definite matrix if \(x^T A x > 0\)Ī positive semidefinite matrix if \(x^T A x \geq 0\)Ī negative definite matrix if \(x^T A x 0 > y^T A y\). That is, the transpose of the matrix of cofactors. Returns the adjugate, or classical adjoint, ofĪ matrix. See determinant.py for their implementations. Provides basic matrix determinant operations. Methods and attribute of Matrix is implemented on one of these baseĭense Matrices, and Sparse Matrices. The Matrix classes are built from functionality in various base classes. Here one might want to look over the matrices.py file for all functionality. So there is quite a bit that can be done with the module including eigenvalues,Įigenvectors, nullspace calculation, cofactor expansion tools, and so on.
