In matlab dividing a wav into frames ,windowing ,fft and getting coefficients

In matlab dividing a wav into frames ,windowing ,fft and getting coefficients

Please could someone help me .I have to write a matlab program in the
editor window to do the following:
read in the wav
then divide it into frames of about 25msec (fs=8000)
then do windowing (mostly hamming window)
then do fft
since the result of fft gives real and imaginary values, and I require
coefficients, we have to use the function abs to the result of the fft,
the coefficients come in the command window.
(There should be about 20 to 50 or may be a few more coefficients) (The
figure has to be shown after each step)
Please could someone write the code because I tried and I am not getting
it. Thank you.
