Newton-Raphson Method for Non-linear System of 3 variables

Newton Method to solve non-linear (also linear) systems of 3 variables.Very amicable

Description

You can solve non-linear systems of 3 variables. Only write "newtonv1" on the command window. Then write the 3 equations, the number of iterations y the precision tolerance. The partial derivatives for the gradients are calculated by the program

• Required Products: Symbolic Math Toolbox
• MATLAB release: MATLAB 6.1 (R12.1)

ok, i've found the problem, that was silly of me. i am getting a warning now, it says
"Warning: The method char/diff will be removed in a future release. Use sym/diff instead. For example diff(sym('x^2')).
After removal diff('x^2') will return diff(double('x^2')).
> In char.diff at 10
In Untitled at 34"
how can i get rid of this warning. Thanks
