generate the following windows for M=128 and 0<=n<=M-1
a)bartlett:w(n)=1-(2n-M-1)/(M-1)
b) Blackman:w(n)=0.42-0.5cos[(2nΠ)/(M-1)]+0.08cos[(4nΠ)/(M-1)]
c)hamming:w(n)=0.54-0.46cos[(2nΠ)/(M-1)]
d)hanning:w(n)=0.5-0.5cos[(2nΠ)/(M-1)]

What is 2n180 and 4n180 ?
Please be aware that MATLAB's sin() and cos() routines work in radians. sind() and cosd() work in degrees.
