Types and constants

Sourcetype ('a, 'b) t = ('a, 'b) Owl_base_dense_ndarray_generic.t

Basic functions

Sourceval inv : ('a, 'b) t -> ('a, 'b) t

``inv x`` calculates the inverse of an invertible square matrix ``x`` such that ``x *@ x = I`` wherein ``I`` is an identity matrix. (If ``x`` is singular, ``inv`` will return a useless result.)

Sourceval det : ('a, 'b) t -> 'a

``det x`` computes the determinant of a square matrix ``x``.

Sourceval logdet : ('a, 'b) t -> 'a

Refer to :doc:`owl_dense_matrix_generic`

Check matrix types

Sourceval is_tril : ('a, 'b) t -> bool

``is_tril x`` returns ``true`` if ``x`` is lower triangular otherwise ``false``.

Sourceval is_triu : ('a, 'b) t -> bool

``is_triu x`` returns ``true`` if ``x`` is upper triangular otherwise ``false``.

Sourceval is_diag : ('a, 'b) t -> bool

``is_diag x`` returns ``true`` if ``x`` is diagonal otherwise ``false``.

Sourceval is_symmetric : ('a, 'b) t -> bool

``is_symmetric x`` returns ``true`` if ``x`` is symmetric otherwise ``false``.

Sourceval is_hermitian : (Complex.t, 'b) t -> bool

``is_hermitian x`` returns ``true`` if ``x`` is hermitian otherwise ``false``.

Factorisation

Sourceval lu : ('a, 'b) t -> ('a, 'b) t * ('a, 'b) t * int array

``lu x -> (l, u, ipiv)`` calculates LU decomposition of ``x``. The pivoting is used by default.
