NAME
larmm - larmm: scale factor to avoid overflow, step in latrs
SYNOPSIS
Functions
double
precision function
dlarmm
(anorm, bnorm, cnorm)
DLARMM
real function
slarmm
(anorm, bnorm, cnorm)
SLARMM
Detailed Description
Function Documentation
double precision function dlarmm (double precision anorm, double precisionbnorm, double precision cnorm)
DLARMM
Purpose:
DLARMM returns a factor s in (0, 1] such that the linear updates
(s * C) - A * (s * B) and (s * C) - (s * A) * B
cannot
overflow, where A, B, and C are matrices of conforming
dimensions.
This is an auxiliary routine so there is no argument checking.
Parameters
ANORM
ANORM is DOUBLE
PRECISION
The infinity norm of A. ANORM >= 0.
The number of rows of the matrix A. M >= 0.
BNORM
BNORM is DOUBLE
PRECISION
The infinity norm of B. BNORM >= 0.
CNORM
CNORM is DOUBLE
PRECISION
The infinity norm of C. CNORM >= 0.
