title: Solving vector equations in Matlab
body: <p>How can I solve a system of this kind in matlab?:<br><br>
  a + b + c = 0<br>
  a + d + e = 0
  ...etc</p>
  
  <p>where each of this symbolic variables (they are previously defined with "syms") is in R^3,
  for example:</p>
  
  <p>a = [0 R1 R2];<br>
  b = [0 R3*cos(alpha) R3*sin(alpha)];</p>
  
  <p>...etc (R1, R2, R3, .. are also symbolic variables, but one dimensional, ie: scalars)</p>
  
  <p>I did search a lot but everyone solves systems of scalars, not of vectors.<br>
  In this case every vector equation represents 3 scalar equations</p>
  
  <p>I know I could reformat the whole system into a matrix and solve Ax=0 but that would be a lot of work since these are 39 equations.</p>
  
  <p>Thank you very much</p>
