using fsolve function to solve for 2 unknowns

1 visualizzazione (ultimi 30 giorni)
I am trying to use the fsolve funstion to solve for 2 unknowns, the3 and theta 4, and I am not sure how
in an .m file I have this:
function F = problem_one(theta)
theta3 = theta(1);
theta4 = theta(2);
f = (2*cosd(30)) + (7*cosd(theta3)) - (9*cosd(theta4)) -6;
g = (2*sind(30)) + (7*sind(theta3)) - (9*sind(theta4));
end
and in a different script file i have this:
x0 = [80,110];
sol = @fsolve[problem_one,x0];
it tells me that my problem_one variable in unrecognized, and also a failure in the inital function objective evaluation. Please help

x0 = [80,110];
[sol, Fsol] = fsolve(@problem_one,x0),
Equation solved. fsolve completed because the vector of function values is near zero as measured by the value of the function tolerance, and the problem appears regular as measured by the gradient.
sol = 1×2
88.8372 117.2861
Fsol = 1×2
1.0e+-6 * -0.3515 0.1394
function F = problem_one(theta)
theta3 = theta(1);
theta4 = theta(2);
F(1) = (2*cosd(30)) + (7*cosd(theta3)) - (9*cosd(theta4)) -6;
F(2) = (2*sind(30)) + (7*sind(theta3)) - (9*sind(theta4));
end
