From: jagdamba prasad prasad on 30 Jun 2010 09:07 Hi, I'm trying to solve a system of ordinary differential equations in symbolic form. i used following command but it returned may error. S=dsolve('Du3 =u4','Du4 =K*b1-(K(x1*t-u3-L)/m)-C(x1-u4)-a1' ,'Du2=K(b1-b2)/C+K(2*u3-u2-x1+L)/C-C(x1-2u4)-(a1-a2)/C') i want to solve for u2,u3 and u4 and rest are symbolic entities . Please tell me what's wrong with above command. Regards JP
