pentaSolve: Solving 'Ax=b' system

In AdvDif4: Solving 1D Advection Bi-Flux Diffusion Equation

Description

This software solves an 'Ax=b' pentadiagonal system using a direct method. Variables a1, a2, a3, a4, a5 are matrix A diags and b is the vector.

Usage

pentaSolve(a1,a2,a3,a4,a5,b)

Arguments

a1	A vector
a2	A vector
a3	A vector
a4	A vector
a5	A vector
b	A vector

Value

A vector with the x value

Examples

#
# Solve a 'Ax=b' easy sample
#
a1<-c(1)
a2<-c(2,2)
a3<-c(7,7,7)
a4<-c(2,2)
a5<-c(1)
b<-c(11,12,13)
