In float: 32-Bit Floats

backsolve

Description

Solve a triangular system.

Usage

## S4 method for signature 'float32,float32'
backsolve(r, x, k = ncol(r), upper.tri = TRUE, transpose = FALSE)

## S4 method for signature 'float32,BaseLinAlg'
backsolve(r, x, k = ncol(r), upper.tri = TRUE, transpose = FALSE)

## S4 method for signature 'BaseLinAlg,float32'
backsolve(r, x, k = ncol(r), upper.tri = TRUE, transpose = FALSE)

## S4 method for signature 'float32,float32'
forwardsolve(l, x, k = ncol(l), upper.tri = FALSE, transpose = FALSE)

## S4 method for signature 'float32,BaseLinAlg'
forwardsolve(l, x, k = ncol(l), upper.tri = FALSE, transpose = FALSE)

## S4 method for signature 'BaseLinAlg,float32'
forwardsolve(l, x, k = ncol(l), upper.tri = FALSE, transpose = FALSE)

Arguments

r, l	A triangular coefficients matrix.
x	The right hand sides.
k	The number of equations (columns of r + rows of x) to use.
upper.tri	Should the upper triangle be used? (if not the lower is)
transpose	Should the transposed coefficients matrix be used? More efficient than manually transposing with t().

Examples

library(float)

s = flrunif(10, 3)
cp = crossprod(s)
y = fl(1:3)
backsolve(cp, y)
