Seismic Signals

This toolbox includes routines for using principal component analysis (PCA) and independent component analysis (ICA) to extract cellular signals from imaging data sets. A full description and validation of the method is provided in the paper, "Automated Analysis of Cellular Signals from...

Computes the Woody average by first aligning individual signals (corrupted by jitter) with the standard average. Uses xcorr to compute the lag and then re-averages the signals to get an improved estimate.Example included in help.Technique deteriorates at low SNRs.

The Fourier Calculator (Simulink model) can be used for arbitrary signals. In this case the Wolfer sun spot data are analyzed

This a very simple function that produces a condensed, approximate version of the time-series signal y, with each group of n adjacent points in y replaced by its average. You can use this to condense over-sampled signals so that subsequent processing will be easier and faster. Or you can use it...

This code provides a tool to identify a state space model from stochastic signals using a subspace approach.The code is implemented in two steps using a nested function. The first step returns a vector of subspace singular values, from which a user can determine an appropriate order for the state...
