collapse all

Create a 64-point rectangular window. Display the result using wvtool.

L = 64;

Figure Window Visualization Tool contains 2 axes objects and other objects of type uimenu, uitoolbar, uipanel. Axes object 1 with title Time domain, xlabel Samples, ylabel Amplitude contains an object of type line. Axes object 2 with title Frequency domain, xlabel Normalized Frequency (\times\pi rad/sample), ylabel Magnitude (dB) contains an object of type line.

Input Arguments

collapse all

Window length, specified as a positive integer.

Data Types: single | double

Output Arguments

collapse all

Rectangular window, returned as a column vector.


The output of the rectwin function with input L can also be created using the ones function.
