# Math Help - solve nonliner equation in matlab

1. ## solve nonliner equation in matlab

Hello my friends
I want to know how I could solve a nonlinear equations using newton's raphson method in matlab

like this equations for example
x>2 + y=37
x-y>2 =5
x+y+z=3

thanks for you help

2. Those are linear. Do you mean "inequalities".

Anyway, solve the Equality and decide which side of the intersection counts. Of course, you must also decide if the intersection itself counts.

Lets assume you mean:

$x^2+y=37$
$x-y^2=5$
$x+y+z=3$

This is a system of equations. In plain ASCII we use "^" to denote a power.
