scalapack_oct_m::scalapack_potrf Interface Reference

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...

Detailed Description

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).

The factorization has the form

\[ sub( A ) = U` U , \mbox{ if UPLO }= 'U' \]

or

\[ sub( A ) = L L` , \mbox{ if UPLO }= 'L', \]

where U is an upper triangular matrix and L is lower triangular.
