How can I solve these six trigonometric equations?

a=70.71;
b=1050;
c=300;
d=260;
e=715.8;
f1=510;
g=380;
h=290;
i=650;
j=46.96;
k=775.1;
l=90.67;
m=324.1;
n=606.4;
o=379.8;
for q=pi/180:pi/180:2*pi

f=@(b)[a*cos(q)+b*cos(b(1))-k-l-c*cos(b(3))
       j+a*sin(q)+b*sin(b(1))-m-c*sin(b(3))
       l+(c+d)*cos(b(3))+e*cos(b(6))-i*cos(b(2))-h*cos(b(4))
       m+(c+d)*sin(b(3))+e*sin(b(6))-i*sin(b(2))-h*sin(b(4))
       l+n+f1*cos(b(5))-i*cos(b(2))-(g+h)*cos(b(4))
       a+f1*sin(b(5))-i*sin(b(2))-(g+h)*sin(b(4))];
   

B0 = rand(6,1)*2*pi;
[B,fv,xf,ops] = fsolve(f, B0);
ps = ['theta1'; 'theta2'; 'theta3'; 'theta4'; 'theta5'; 'theta6'];
fprintf(1, '\n\tParameters:\n')
for k1 = 1:length(B)
    fprintf(1, '\t\t%s = % .4f\n', ps(k1,:), B(k1))
end
end

What is wrong with your current method? The code runs for me without error messages.
