This function will take a matrix designed to be used by the Gauss-Jordan algorithm and solve it.

软件应用简介

Description: 

This function will take a matrix designed to be used by the 

Gauss-Jordan algorithm and solve it, returning a transposed 

version of the last column in the ending matrix which 

represents the solution to the unknown variables.

Input: 

The function takes one matrix of n by n+1, where n equals 

the number of unknown variables. Each row represents the 

coefficients of the variables in each equation and the last 

column contains the constants on the right hand side of 

each equation.

Output: 

The function will return a column vector representing 

the solution to each variable in order of appearance in the 

given matrix.

Sample Input: 

x = [1 3 1 10; 1 -2 -1 -6; 2 1 2 10]; 

gauss(x)

Sample Output: 

ans =

1.0000 2.0000 3.0000
