Solving a system of linear equations question.

[EDIT: Wed Jun 15 04:15:02 UTC 2011 - Reformat - MKF]

 hey . how i solve this linear equations (ODE) in matlab 

x+y-2=-2z  
3x+z=y+6
x+3y+4z-4=0

[John D'Errico]

How is this an ODE? An ODE is a differential equation. Where are the derivatives?

It's an ode like a poem...

First, set the equations up as matrices. So, if you had the following equations:

 5*x + 2*y = 10
 x = 2

You would convert this to matrix form:

 Ax = b
 A = [ 5 2 ; 1 0 ]
 b = [ 10 ; 2 ]

Finally, you can solve for this system of equations in MATLAB using the BACKSLASH operator:

 x = A\b

And x will contain the variables x and y. Just follow these steps to solve for your system. Good luck!
