With the instruction "h = firpm(n, f, a);", can you give example to show ho to determine the parameters n,f &a?

I have read the document about "firpm", but I am still not quite sure on how to determine its parameters, especially when having a signal.wav. Does n represents the order of the LP filter? How about f & a?
Thanks

Help doc is clear enough.
The only point that maybe causes a confusion you is the "order" n.
So keep in mind that firpm(n, f, a) returns a FIR filter with n+1 taps.
