Urgent help for fsolve

[skazmi]

i am trying to optimize these two non-linear equations,

i dont know where is the bug can any one help.

global x y
function [one, two] = f (x, y)
  one = (x^-1.3)*P - 1.2*(1-y)^-3.6; 
  two = 2+3*y-x; 
  three = [one two]'
return;
endfunction 

[[x, y], fval, info] = fsolve (@f, [1; 2])
