>> a("a")

What you have tried is correct - it works fine on my working copies of 
octave-2.1.50 and 2.1.64.

In octave-forge you will find getfield and setfield that do the same job, a 
la Matlab.  The .m version of both of these use the construct that you 
tried.

Thus

a.("a") = 1.0;
a.("b") = 2.0;
a.("c") = 3.0;
disp (all ([a.("a") == a.a, a.("b") == a.b, a.("c") == a.c]))

Should display 1.
