The bohman_window
command applies the Bohman window function to a sequence or its segment.
- 
bohman_window takes one mandatory argument
and two optional arguments:
- 
v, a real vector with length n.
- Optionally, m, N, a sequence of two integers (by default, m=0 and N=n).
 
- bohman_window
returns the elementwise product of [vm,vm+1,…,vm+N−1]
and the vector w of length N defined by
| wk= | ⎛ ⎝
 | 1−xk | ⎞ ⎠
 | cos | ⎛ ⎝
 | π xk | ⎞ ⎠
 | + |  | sin | ⎛ ⎝
 | π xk | ⎞ ⎠
 | , |  
 where xk=|2 k/N−1−1| for k=0,1,…,N−1.
Example
| listplot(bohman_window([1$1000])) |
