Function File: expwin (m, alpha)
Function File: expwin (m, sll)
Function File: expwin (…, "canonical")

Return the coefficients of an exponential window1 of length m.

The window’s adjustable parameter can be set directly as alpha (≥0) or indirectly with sll (<0), the latter being the desired side-lobe level in dBc.

By default, the returned window is both symmetric and periodic. With the optional argument "canonical", the canonical form of the window is returned, which is symmetric but not periodic.
