fdst() returns the fast discrete S-transform, S, as a lambda function, and
requires the length of the signal to be transformed. The function pre-
computes the Gaussian window for the transform.
The image is generated from the example script in the header.

3.0.0.0

This update reflects that the script produces the discrete Stockwell transform, not the discrete orthogonal Stockwell transform.
Corrected two errors from original transform implementation. The code here is a correct S-transform that satisfies the marginals.
2.0.0.0

Changed name from dst.m to not conflict with discrete sine transform.
Added processing for complex vector
