[Algorithm] Lomb-Scargle DL : 0: FASTLOMB caculates the Lomb normalized periodogram (aka Lomb-Scargle, Gauss-Vanicek or Least-Squares spectrum) of a vector x with coordinates in t. The coordinates need not be equally spaced. In fact if they are, it is probably preferable to use PWELCH or SPECTRUM. For more details on the Lomb normalized periodogram, see the excellent section 13.8 in [1], pp. 569-577. This code is a transcription of the Fortran subroutine fasper in [1] (pp.575-577), so it is a really fast (albeit not really exact) implementation of the Lomb periodogram. Also Matlab s characteristics have been taken into account in order to make it even faster for Matlab. For an exact calculation of the Lomb periodogram use LOMB, which is however about 100 times slower.-FASTLOMB caculates the Lomb normalized periodogram (aka Lomb-Scargle, Gauss-Vanicek or Least-Squares spectrum) of a vector x with coordinates in t.

[matlab] matlab的pwelch函数 DL : 0: Welch法对Bartlett法进行了两方面的修正，一是选择适当的窗函数w(n)，并再周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时，可使各段之间有重叠，这样会使方差减小。以下是Matlab代码示例：
