[scilab-Users] feval an external function

Are you sure that this what you want to do? Under scilab feval is used 
to evaluate an external function on several arguments (see help page). 
This is different than matlab© function feval.

If I understand your problem, you want to pass a function (bar) as an 
argument to another function (foo) and evaluate it, right?

The good new is that scilab functions are variables so you can pass the 
function bar as an argument (without quotes). Let's say that the 
argument name is bar_function. Then you can simply write (inside foo)  
bar_function(args).

See chapter 6 of "An Introduction to Scilab from a Matlab User's Point 
of View" by Eike Rietsch on scilab website 
(http://www.scilab.org/en/support/documentation/community).

I have attached a dummy example (where the function to call is called 
bars to avoid erasing the predefined bar)

HTH,
Mathieu
