    Hello my friends
    I need your help
    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

    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.
