title: Error when solving symbolic system of ODEs using dsolve
body: <p>I have been trying to use the command <code>dsolve</code> in Matlab to solve a set of ODEs, but I am getting these errors:</p>
  
  <blockquote>
    <p>Error in dsolve>mupadDsolve (line 332)
    T = feval(symengine,'symobj::dsolve',sys,x,options);</p>
    
    <p>Error in dsolve (line 193)
    sol = mupadDsolve(args, options);</p>
  </blockquote>
  
  <p>Below is the code if someone wants to take a look at it:</p>
  
  <pre><code>syms t b1 b2 k1 k2;
  A=0.5;
  m1=3;m2=4;w=6;
  y=A*sin(w*t);
  xt=dsolve('m1*D2x1+b1*((Dx1)-Dy)+k1*(x1-y)+b2*((Dx1)-(Dx2))+k2*(x1-x2)=0','m2*D2x2+b2*((Dx2)-(Dx1))+k2*(x2-   x1)=0','x1(0)=0','Dx1(0)=0','x2(0)=0','Dx2(0)=0');
  </code></pre>
  
  <p>Could someone please help me with that?</p>
  
  <p>Thank you all very much</p>
