f(a,b,c,d)

can be considered as a function that takes 4 separate arguments named a,b,c, and d, or f can be considered as a function that takes a single argument: a list consisting of 4 items.

Han,
if I input [a,b], there is a way (in CAS) to tell the program that this input should be a matrix or vector and *not* a list? or other trick to do that?
In my program for Wronskian I would like threat only input like [x, x^2, ...] not also {...} or x,x^2,... if it's possible.

Thank you!
