**convolution in matlab without using conv**

hi!

i am suppose to design a low pass filter(lpf) using any window methods without uisng built-in functions in matlab. and the output should be a frequency response of the filter.

i could find coefficients of window(simply by substituting the formula for one of the windows) but designing the lpf without using the built-in functions has been very irritating !!

if anyone could help me concerned with this i will be very thankful!!!

thank you!
