I don't think that's what he actually wants:

octave:1> thing_a = 2;
octave:2> x = sprintf("%d",thing_a)
x = 2
octave:3> class(x)
ans = char

i.e. x is a string variable containing the char "2"
I guess he wants to do:

octave:4>y = "thing_a"
octave:5> x = eval(y)
x =  2
octave:6>class(x)
ans = double

x is now the number 2

c.

This would give

x == "2" (class ), not x == 2

You should eval
