the tutorial is not helpful for me. I tried to write a code like below but its giving error. could u pls correct it?
function f=nle(x)
f(1)=x(1)-4*x(1)^2-x(1)*x(2);
f(2)=2*x(2)-x(2)^2+3*x(1)*x(2);
end
x0=[1 1];
x=fsolve('nle';x0)
You missed a sentence,
"Enter the initial guess
x0 = [1 1]'
Note: x0 is the TRANSPOSE of a row vector"
You did not use the transpose.
