	This module contains interfaces for ScaLAPACK routines Interfaces are from http:

Data Types
interface	scalapack_oct_m::iceil
interface	scalapack_oct_m::descinit
interface	scalapack_oct_m::infog2l
interface	scalapack_oct_m::scalapack_geqrf
	Computes a QR factorization of a real distributed \( m \times n\). More...
interface	scalapack_oct_m::scalapack_orgqr
	Generates an \( m \times n\) real distributed matrix Q denoting A(IA:IA+M-1,JA:JA+N-1) with orthonormal columns, which is defined as the first N columns of a product of K elementary reflectors of order M. More...
interface	scalapack_oct_m::pdgesv
interface	scalapack_oct_m::pzgesv
interface	scalapack_oct_m::scalapack_syev
	Computes all eigenvalues and, optionally, eigenvectors of a real symmetric matrix A by calling the recommended sequence of ScaLAPACK routines. More...
interface	scalapack_oct_m::scalapack_syevx
	Computes selected eigenvalues and, optionally, eigenvectors of a real symmetric matrix A by calling the recommended sequence of ScaLAPACK routines. Eigenvalues/vectors can be selected by specifying a range of values or a range of indices for the desired eigenvalues. More...
interface	scalapack_oct_m::scalapack_sygvx
	Computes all the eigenvalues, and optionally, the eigenvectors of a real generalized SY-definite eigenproblem, of the form \( sub( A ) x=(\lambda) sub( B ) x, sub( A ) sub( B ) x=(\lambda) x, \mbox{ or } sub( B ) sub( A ) x=(\lambda) x \). Here sub(A) denoting A(IA:IA+N-1, JA:JA+N-1) is assumed to be SY, and sub(B) denoting B(IB:IB+N-1, JB:JB+N-1) is assumed to be symmetric positive definite. More...
interface	scalapack_oct_m::scalapack_hegvx
	Computes all the eigenvalues, and optionally, the eigenvectors of a complex generalized Hermitian-definite eigenproblem, of the form \( sub( A ) x=(\lambda) sub( B ) x, sub( A ) sub( B ) x=(\lambda) x, \mbox{ or } sub( B ) sub( A ) x=(\lambda) x \). Here sub(A) denoting A(IA:IA+N-1, JA:JA+N-1) is assumed to be Hermitian, and sub(B) denoting B(IB:IB+N-1, JB:JB+N-1) is assumed to be Hermitian positive definite. More...
interface	scalapack_oct_m::scalapack_potrf
	Computes the Cholesky factorization of an \( n \times n \) real symmetric positive definite distributed matrix sub(A) denoting A(IA:IA+N-1, JA:JA+N-1). More...
