bandsolpd ============================================== Purpose ---------------- Solves the system of equations :math:`Ax = b` for *x*, where *A* is a positive definite banded matrix. Format ---------------- .. function:: x = bandsolpd(b, A) :param b: :type b: KxM matrix :param A: :type A: KxN compact form matrix :return x: :rtype x: KxM matrix Remarks ------- *A* is a positive definite banded matrix in compact form. See :func:`band` for a description of the format of *A*. *b* can have more than one column. If so, :math:`Ax = b` is solved for each column. That is, .. math:: A*x[.,i] = b[.,i] .. seealso:: Functions :func:`band`, :func:`bandchol`, :func:`bandcholsol`, :func:`bandltsol`, :func:`bandrv`
