Here is one online tutorial

[Mohammad Yunus Ali]

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.
