4.9.3 More methods

In the examples so far, you met a couple of methods for computational tasks in linear algebra, for example, solve. More methods are available after the command import scipy.linalg as sl is executed. The most common of them are listed in Table 4.6:

Methods Description
sl.det Determinant of a matrix
sl.eig Eigenvalues and eigenvectors of a matrix
sl.inv Matrix inverse
sl.pinv Matrix pseudoinverse
sl.norm Matrix or vector norm
sl.svd Singular value decomposition
sl.lu LU decomposition
sl.qr QR decomposition
sl.cholesky Cholesky decomposition
sl.solve Solution of a general or symmetric linear system: Ax = b
sl.solve.banded The same for banded matrices
sl.lstsq Least squares solution
Table 4.6: Linear algebra functions of the module scipy.linalg

Execute import scipy.linalg as sl first.
