Bandwidth
Return the spectral density estimator given a data vector X, 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.
