Solve nonlinear equation system with parameter in Matlab

Question

How to modify the code if I add parameter c to function Thank for help

x0 = [0,0];
x = fsolve(@myfunc,x0)
%===================
function F = myfunc(x)
F(1) = 4*c*(c*x(1) - 2)^3 + 2*c*x(2)^2 *(c*x(1)-2);
F(2) = 2*x(2)*(cx(1) - 2)^2 + 2*(x(2)+1);
end

Answer 1

1. Change the function line as following: function F = myfunc(x, c)
2. Change x execution part:

x = fsolve(@(x) myfunc(x, c), x0)

3. Create a new function x(c):

function x = x_func(c)
    x0 = [0,0];
    x = fsolve(@(x) myfunc(x, c), x0);
end

4. Use your inputs:

c = 6;
x = x_func(c);
x1 = 2/c;
x2 = -1;
