# L — window length
+
positive integer
Details
The window length specified as a positive integer.
If you set L as a non-integer number, the function will round it to the nearest integer value.

# r — cosine fraction
+
0.5 (by default) | real scalar
Details
A cosine fraction given as a real scalar. The Tukey window is a rectangular window in which the first and last r/2 percentages of samples are equal to fractions of cosine. For example, when r = 0.5 it turns out a Tukey window in which 1/2 The entire length of the window consists of segments of a phase-shifted cosine with a period 2r = 1. If you set r ≤ 0, returns L-dotted rectangular window. If you set r ≥ 1, returns L- von Hahn point window.

The following equation defines -Tuki point window:
Where — a linearly spaced vector from points. Parameter — the ratio of the length of the cosine section to the total length of the window, where . For example, when it turns out a Tukey window in which The entire length of the window consists of segments of a phase-shifted cosine with a period . If you ask , returns -dotted rectangular window. If you ask , returns - von Hahn point window.
