Hi Dear all, I have the problem in solving the non-linear equations. My code is as follows- The code is : %========================================================================== 27 MAR 2014 % x(1)= x % x(2)= y %++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Eqs = @(x,y) [(((1+2.*x(1).^2)./(1-x(1).^2))+(4.*(1-2.*x(2).^2).*sqrt(1-x(1).^2).*(2+x(1).^2))./((1-x(1).^2).*(1-x(2).^2).^0.5.*(2+x(2).^2)));... (((4.*(x(2).*(2+x(1).^2).*(1-x(1).^2).*sqrt(pi.^2.*(1-x(2).^2)+4.*x(2).^2)))./(x(1).*(2+x(2).^2).*(1-x(2).^2).*sqrt(pi.^2.*(1- x(1).^2)+4.*x(1).^2))-1))]; %========================================================================== xy = []; Eqval = []; for k1 = [0.25 0.25] % Guess Values [p, fval] = fsolve(Eqs,[k1; k1]); xy = [xy p]; Eqval = [Eqval fval]; end xy Eqval %@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ When i ran the above code, i got the following message
Maximum number of function evaluations reached: increase options.MaxFunEvals.
xy = 1.0e-005 * -0.8410 -0.8410 -0.2102 -0.2102 Eqval = 5.0000 5.0000 -0.0000 -0.0000
Kindly suggest me to get the correct roots of the above TWO NON-LINEAR Equations.
