The function returns the solution of three equations in three variables using the Newton-Raphson method. The inputs are symbolic functions, initial guesses and number of iterations.

Here's an example;
syms x y z
u=3*x-cos(y*z)-1.5; v=4*x-625*(y^2)+2*z-1; w=20*z+exp(-x*y)+9;
xo=1;yo=2;zo=3;n=20,
Newton_Raphson(u,v,w,xo,yo,zo,n)
