MATLAB HELP PLEASE! NEED HELP MAKING THESE FILTERS, FOR SOME REASON I KEEP GETTING WRONG DATA

Rectangular window. Write a function rectfilt that creates an FIR filter of order, N, and cutoff frequency omega_c based on a rectangular window: function h = rectfilt (N, wc) % RECTFILT Creates Rectangular filter. % h = rectfilt (N, wc) % returns filter of order N and cutoff wc % based on rectangular window, wc is in fractions % of pi. Hamming window. Write a function hammingfilt that creates an FIR filter of order, N, and cutoff frequency omega_c based on a hamming window: function h = hammingfilt(N, wc) % HAMMINGFILT Creates Hamming FIR filter. % h = hammingfilt(N, wc) % returns filter of order N and cutoff wc % based on hamming window, wc is in fractions % of pi.
