Brown Noise Sample

USAGE: noise=fftnoise(f[,Nseries]) INPUTS: f: the fft of a time series (must be a column vector) Nseries: number of noise series to generate. (default=1) OUTPUT: noise: surrogate series with same power spectrum as f. (each column is a surrogate). ------ Example: ------ %calculate if the trend is...

This was inspired by kstest2 from the matlab statistics toolbox.Works from medium to large sample sizes, look at the references in the code

This short code calculates the sample entropy (SampEn) of a given time series data. SampEn is a measure of complexity that can be easily applied to any type of time series data, including physiological data such as heart rate variability and EEG data.SampEn is conceptually similar to approximate...

This small contribution is useful in cases where you search for the position of a peak within an intensity matrix (correlation or energy fields) of low resolution. Since this is only a 2nd-order-fit the sub-sample accuracy will only be acceptable as long as the peak area is 'smooth' around the...

Noise Level Calculation Noise Level Many types of noise can be eliminated during data collection or post-processing. Noise removal during data collection is preferable. Noise that cannot be removed will increase Sv measurements and bias in situ TS measurements, leading to errors in fish density...
