Error using sym, too many input arguments
显示 更早的评论
So, I've been trying to solve this nonlinear complex 12x12 equation system
sym l2x l2y l3x l3y phi1 phi2 phi3 phi4 phi5 phi6 l1x l1y
e1=l1x*(exp(-i*alfa(1))-1)+l2x*(exp(-i*phi1))-l3x*(exp(-i*rho(1)));
e2=l1y*(exp(-i*alfa(1))-1)+l2y*(exp(-i*phi1))-l3y*(exp(-i*rho(1)));
e3=l1x*(exp(-i*alfa(2))-1)+l2x*(exp(-i*phi2))-l3x*(exp(-i*rho(2)));
e4=l1y*(exp(-i*alfa(2))-1)+l2y*(exp(-i*phi2))-l3y*(exp(-i*rho(2)));
e5=l1x*(exp(-i*alfa(3))-1)+l2x*(exp(-i*phi3))-l3x*(exp(-i*rho(3)));
e6=l1y*(exp(-i*alfa(3))-1)+l2y*(exp(-i*phi3))-l3y*(exp(-i*rho(3)));
e7=l1x*(exp(-i*alfa(4))-1)+l2x*(exp(-i*phi4))-l3x*(exp(-i*rho(4)));
e8=l1y*(exp(-i*alfa(4))-1)+l2y*(exp(-i*phi4))-l3y*(exp(-i*rho(4)));
e9=l1x*(exp(-i*alfa(5))-1)+l2x*(exp(-i*phi5))-l3x*(exp(-i*rho(5)));
e10=l1y*(exp(-i*alfa(5))-1)+l2y*(exp(-i*phi5))-l3y*(exp(-i*rho(5)));
e11=l1x*(exp(-i*alfa(6))-1)+l2x*(exp(-i*phi6))-l3x*(exp(-i*rho(6)));
e12=l1y*(exp(-i*alfa(6))-1)+l2y*(exp(-i*phi6))-l3y*(exp(-i*rho(6)));
result=solve(e1,e2,e3,e4,e5,e6,e7,e8,e9,e10,e11,e12)
Sadly I have an error, it says error usingSyms, too many input arguments
Here's the full code:
%Point imput and reference axis change

L=82.4;
L1=35.7;
L2=39.7;
Px=[3.83066 20.5384 -25.4442 -18.651 -7.17219 11.2119 -3.91001];

for j=1:7
PX(j)=Px(j);
PY(j)=Py(j)-L;
end
% Angles
for j=1:7
f = @(theta) [L1*cos(theta(1))+L2*cos(theta(2))-PX(j); L1*sin(theta(1))+L2*sin(theta(2))-PY(j)];
p=[0.24 0.245];
thetA=fsolve(f,p);
Theta1(j)=thetA(1);
Theta2(j)=thetA(2);
Theta1_Grados(j)=360+Theta1(j)*(360/(2*3.141516))
Theta2_Grados(j)=360+Theta2(j)*(360/(2*3.141516))
end
for j=1:6
alfa(j)=Theta1(j+1)-Theta1(j);
rho(j)=alfa(j)+0.17;
end

Replace sym with syms.
Instead of i (complex number) 1i is preferred.
