LONG2FIR - Cut LONG window to FIR

Usage

g=long2fir(g,L);

Description

long2fir(g,L) will cut the LONG window g to a length L FIR window by cutting out the middle part. Note that this is a slightly different behaviour than middlepad.

long2fir(g,L,'wp') or long2fir(g,L,'hp') does the same assuming the input window is a whole-point even or half-point even window, respectively.
