error: can't perform indexing operations for <unknown type> type

I get this error during a shooting algorithm as part of a simulation when 
variables are returned from a function.  As a test I wrote the simplest 
possible function call:

clear all
A=2;
d = others(A)

%%%%%%%%%%%%%%

function d = others(A)
d=A^2;
return

and still get the error message! 
The program returns a value consistent with the function, so variables are 
being passed, but then octave prints out the error message when I quit the 
program.  Am I doing something idiotic?
