When i run this script i got this error:
error: A(I): Index exceeds matrix dimension.
By your fsolve() invocation, the parameter vector length is 2, but in
the function you use x(3).
When you call [x, info] = fsolve (@f, [1; 3]);
it still doesn't work, but the error message is different, at least :)
