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 in RunMat

• hamming(L) returns an L x 1 symmetric Hamming window.
• hamming(L, 'periodic') returns the periodic form used in spectral-analysis workflows.
• If L is noninteger, RunMat rounds it to the nearest integer before constructing the window.
• hamming(0) returns an empty 0 x 1 tensor.
• hamming(1) returns 1.
• For the symmetric case and L > 1, coefficients follow 0.54 - 0.46*cos(2*pi*n/(L-1)).
• The periodic form is constructed by evaluating a symmetric window of length L + 1 and 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.
