FIR filter probs, PLZ Help!

[hustlercreed]

hey guys im new here and to matlab and ive got a question-

does anyone have like a sample of the matlab code that i would use to dtermine the correct order of a filter ( we've been given the stopband freq, passband freq ) for a kaiser window and a hamming window . I know that there's a function called kasier_ord.m / hamming_ord.m that will do this for me However i need to sort of write that function in matlab code.

thnx guys

you can use fdatool in matlab for your solution

but how do i view the matlab code

Added after 5 minutes:

basically i need the code forthe function kaiser_ord

in fdatool is run in gui mode it easy to use and you can see the frequency response
gain and etc. then you can use fdatool for generate m file.you can see for more example in this link
