Return the spectral density estimator given a vector of autocovariances c, window name win, and bandwidth, b.
The window name, e.g., "triangle"
or "rectangle"
is
used to search for a function called win_lw
.
If win is omitted, the triangle window is used.
If b is omitted, 1 / sqrt (length (x))
is used.
