Is there a difference between creating matrix directly and using list2mat?

The following demonstrates what I found:

eq1:=m*(s^2*x-s*dx0-x0)+b*(s*x-x0)+k*x=0
vars:=[ m=2, b=8, k=26, xo=1, dx0=0 ] :;
vars1:=list2mat(vars,1)
subs(eq1,vars)
subs(eq1,vars1)

Note that substituting vars works, substituting vars1 does not.

Thank you,
Matt

list2mat(.,1) creates a matrix with 1 column, that's different from vars1 which is a list.
With version 0.9.1 both subst work.

Version 0.9.0 fixed my problem! Thank you very much.
