Vector vector - The vector to use as input to the spectrogram.
number freq - The frequency for the spectrogram.
boolean average - [OPTIONAL]
number len - The base 2 logarithm of the length of the power spectrum. Should be an integer >= 4. [OPTIONAL]
boolean apodize - If true, sharp discontinuities are removed. [OPTIONAL]
boolean removeMean - True if the mean should be removed before performing the transform. [OPTIONAL]


Creates a new power spectrum (PSD) object in Kst. Units are V and Hz by default.

The input vector for the spectrogram.

Contains the base 2 logarithm of the length of the spectrogram. Should be an integer >= 4.

the normalization for the transform:

• 0 - amplitude spectral density
• 1 - power spectral density
• 2 - amplitude spectrum
• 3 - power spectrum

True if the mean should be removed before performing the transform.

If true, sharp discontinuities are removed.

The apodization function to be used in the case that apodize is true:

• 0 - default
• 1 - bartlett
• 2 - blackman
• 3 - connes
• 4 - cosine
• 5 - gaussian
• 6 - hamming
• 7 - hann
• 8 - welch
• 9 - uniform

Contains the sampling rate of the spectrogram.

The matrix for the spectrogram.

A string containing the units for the vector.

A string containing the units for the rate.

The window size of the spectrogram.

True if the transform should automatically interpolate over missing data values.
