I don't know of any inline() function for Octave, but you can define
new functions with eval(). You can then use its name (a string) as a
pointer to the function, and call it with feval(). Example :
## myfun() is defined as a global function
eval ("function y = myfun (x), y = x.^2; end;")
y = feval ("myfun", xx);
# One can then pass this function as an argument to another
# function:
#
# x = foo(fun,...);
#
# So my question is, is there an equivalent construction in
# Octave? If not, what is the best way to pass functions as
# arguments?
Currently, use a string holding the function name.
Hth,
Etienne
