I'm having trouble using fzero on this function:
function out = f(theta)L1 = 2; L2 = sqrt(2); L3 = sqrt(2);g = pi/2;p1 = sqrt(5); p2 = sqrt(5); p3 = sqrt(5);x1 = 4; x2 = 0; y2 = 4;A2 = L3*cos(theta) - x1;B2 = L3*sin(theta);A3 = L2*cos(theta + g) - x2;B3 = L2*sin(theta + g) - y2;D = 2*(A2*B3 - B2*A3);N1 = B3*(p2^2 - p1^2 - A2^2 - B2^2) - B2*(p3^2 - p1^2 - A3^2 - B3^2);N2 =-A3*(p2^2 - p1^2 - A2^2 - B2^2) + A2*(p3^2 - p1^2 - A3^2 - B3^2);out = N1^2 + N2^2 - (p1^2)*(D^2);
What I'm doing is inputting this in the command window:
>> fzero(f,-1)
I have saved the function in an m-file as 'f.m'. And I'm obtening the following error:
Not enough input arguments.Error in f (line 8)A2 = L3*cos(theta) - x1;
Am I doing something wrong? I will attach the m-file just in case.
