23 Mar 2014 Newton-Raphson Method for 2 variables Newton method for non-linear system of 2 variables (also solves linear system) Author: Jesus Hernandez Soni, Sandeep

When i am running your code for following equations,roots are not correct .Kindly help me.
f1(x,y) = '(((1+2*x^2)/(1-x^2))+(4*(1-2*y^2)*sqrt(1-x^2)*(2+x^2))/((1-x^2)*(1-y^2)^0.5*(2+y^2)))'

f2(x,y) = '(((4*(y*(2+x^2)*(1-x^2)*sqrt(pi^2*(1-y^2)+4*y^2)))/(x*(2+y^2)*(1-y^2)*sqrt(pi^2*(1-x^2)+4*x^2))-1))'

The initial values are xo = 0.10 and yo = 0.10
The maximun number of iteration is k = 100
and the tolerance is: 1.00e-007

The Root are:
x = 5.7355e+054 +5.3264e+053i
y = 5.7207e+054 +5.3127e+053i

Otherwise your code very excellent.

Thanks,

i keep getting this message.
!Error using diff
Difference order N must be a positive integer scalar.
Error in newton3v1 (line 35)
gradf1 = [diff(f1name,'x') diff(f1name,'y') diff(f1name,'z')];!

please help

@Hernandez

can u plz post the m file code for 4 variables?

EMRE before running the program try
>> syms x y

EKTOR
diff(f,n) means give me the nth derivative of f, and thats why it needs to be integer..
