how to use window function with matched filter in m file

using a filter m-file

i dont know how to use any of window function to suppress the sidelobes of matched filter.I need help please.:idea:

digital matched filter

You can use function conv if you have vector with impuls response of your window function. Or function filter if you have object.

Example 4.11.
Given the sinusoid


obtained by using a sampling rate of fs = 8,000 Hz, use the DFT to compute the
spectrum with the following specifications:

a. Compute the spectrum of a triangular window function with a window
size = 50.
b. Compute the spectrum of a Hamming window function with a window
size = 100.
c. Compute the spectrum of a Hanning window function with a window
size = 150 and one-sided spectrum.

The MATLAB program is listed in Program 4.2, and the results are plotted in
Figures 4.19 to 4.21. As compared with the no-windowed (rectangular window)
case, all three windows are able to effectively reduce spectral leakage, as shown
in the figures.

matched filter function

one other easy way is go to start menu of MATLAB, go to toolboxes/filterdesign/fda tool, from there you can use window according to your requirement, using fda tool going in file menu you can also generate m file of the designed filter.
