In wrathematics/pbdDMAT: 'pbdR' Distributed Matrix Methods

Compute or estimate the Condition Number of a Distributed Matrix

Description

Computes or estimates the condition number.

Usage

## S3 method for class 'ddmatrix'
kappa(z, exact = FALSE, norm = NULL, method = c("qr", "direct"), ...)

## S4 method for signature 'ddmatrix'
rcond(x, norm = c("O", "I", "1"), triangular = FALSE, ...)

Arguments

exact	logical. Determines whether exact condition number or approximation should be computed.
norm	character. Determines which matrix norm is to be used.
method	character. Determines the method use in computing condition number.
...	Extra arguments.
x, z	numeric distributed matrices.
triangular	logical. If true, only the lower triangle is used.

Value

Returns a number.
