Syms Error
Posted:
Dec 9, 2012 2:56 PM


I am wanting to row reduce a matrix that was combined with a matrix that was created using integration with the syms s function. However, when I attempt to row reduce I get this error:
Error using sym/rref Too many input arguments.
Is there a way to avoid this error by using a different integration technique? Below is my code for that relates to this question. Thank you in advance for any advice or suggestions.
%Source Lines syms s i=0; i=1+i:n; xxu(i)=x(1,i)+sin(Phi(1,:)).*s; xxl(i)=x(2,i)+sin(Phi(1,:)).*s; zzu(i)=z(1,i)+cos(Phi(2,:)).*s; zzl(i)=z(2,i)+cos(Phi(2,:)).*s; xx=[xxu;xxl]; zz=[zzu;zzl];
%Combine Upper and Lower Matricies
x=[x(1,:) x(2,:)]; z=[z(1,:) z(2,:)]; xmid=[xmid(1,:) xmid(2,:)]; zmid=[zmid(1,:) zmid(2,:)]; Phi=[Phi(1,:) Phi(2,:)]; Theta=[Theta(1,:) Theta(2,:)]; L=[L(1,:) L(2,:)]; xx=[xx(1,:) xx(2,:)]; zz=[zz(1,:) zz(2,:)];
%Function to be integrated and Integration for i=1:N; for j=1:N; X(i,j)=(xmid(i)xx(j)); Z(i,j)=(zmid(i)xx(j)); F(i,j)=((X(i,j)).*cos(Theta(i))+(Z(i,j)).*sin(Theta(i)))./((X(i,j)).^2+(Z(i,j)).^2); I(i,j)=int(F(i,j),s,0,L(j)) vpa(I) end end
I = round(I*1e4) / 1e4;
Equalmatrix=[V*sin(Theta(1)angle);V*sin(Theta(2)angle); V*sin(Theta(3)angle); V*sin(Theta(4)angle); V*sin(Theta(5)angle); V*sin(Theta(6)angle); V*sin(Theta(7)angle); V*sin(Theta(8)angle)];
CP=rref(I,Equalmatrix);
