        -------------------------
        Linear algebra basics:
    
        - norm            Vector or matrix norm
        - inv             Inverse of a square matrix
        - solve           Solve a linear system of equations
        - det             Determinant of a square matrix
        - lstsq           Solve linear least-squares problem
        - pinv            Pseudo-inverse (Moore-Penrose) calculated using a singular
                          value decomposition
        - matrix_power    Integer power of a square matrix
    
        Eigenvalues and decompositions:
    
        - eig             Eigenvalues and vectors of a square matrix
        - eigh            Eigenvalues and eigenvectors of a Hermitian matrix
        - eigvals         Eigenvalues of a square matrix
        - eigvalsh        Eigenvalues of a Hermitian matrix
        - qr              QR decomposition of a matrix
        - svd             Singular value decomposition of a matrix
        - cholesky        Cholesky decomposition of a matrix
    
        Tensor operations:
    
        - tensorsolve     Solve a linear tensor equation
        - tensorinv       Calculate an inverse of a tensor
    
        Exceptions:
