hamming — Generate a Hamming window as an N-by-1 real column vector.
hamming generates Hamming windows for signal-processing workflows such as spectral analysis and filter design. RunMat supports the standard MATLAB symmetric and periodic forms.
How hamming works
hamming(L)returns anL x 1symmetric Hamming window.hamming(L, 'periodic')returns the periodic form used in spectral-analysis workflows.- If
Lis noninteger, RunMat rounds it to the nearest integer before constructing the window. hamming(0)returns an empty0 x 1tensor.hamming(1)returns1.- For the symmetric case and
L > 1, coefficients follow0.54 - 0.46*cos(2*pi*n/(L-1)). - The periodic form is constructed by evaluating a symmetric window of length
L + 1and dropping the final sample.
Examples
Generate a short Hamming window
w = hamming(8);
disp(w')Generate a periodic Hamming window
w = hamming(8, 'periodic');
disp(w')FAQ
When should I use the periodic Hamming window?⌄
Use 'periodic' when the window will be paired with FFT-based spectral analysis. The periodic form is built from a symmetric window of length L + 1 with the final sample removed.
What shape does hamming(L) return?⌄
It returns an L x 1 column vector.
Does RunMat support a typeName overload for hamming?⌄
RunMat currently implements the documented hamming(L) and hamming(L, sflag) forms.
