Subject: Syms Error

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/rrefToo 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 Linessyms si=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 Matriciesx=[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 Integrationfor 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)    endendI = 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);
