HI all

Is there a trick to do this in MATLAB ?

[R1 R2 R3 VA VB VG]=[8 2 4 12 -6 0]

I want to assign to all sym variables the values on right

 V = num2cell([8 2 4 12 -6 0]);
 [R1 R2 R3 VA VB VG] = deal(V{:});

This does not have anything to do with the symbolic toolbox ? Or are you wanting to subs() like that? If so then

subs(TheExpression, [R1 R2 R3 VA VB VG], [8 2 4 12 -6 0])

   V = num2cell([8 2 4 12 -6 0]);
   [R1 R2 R3 VA VB VG] = deal(V{:});

Worked, but the code is ugly :(

Yes, unfortunately cell expansion cannot be done on an expression
