scipy.linalg.cho_solve

scipy.linalg.cho_solve(clow, b)

Solve a previously factored symmetric system of equations.

The equation system is

A x = b, A = U^H U = L L^H

and A is real symmetric or complex Hermitian.

Parameters:

clow : tuple (c, lower)

Cholesky factor and a flag indicating whether it is lower triangular. The return value from cho_factor can be used.

b : array

Right-hand side of the equation system

First input is a tuple (LorU, lower) which is the output to cho_factor. :

Second input is the right-hand side. :

Returns:

x : array

Solution to the equation system
