>> Y = cummean(X,DIM);if X is MxN, Y is also MxN. To illustrate the functionality, lets assume X is a 1xN vector. Then, Y is a 1xN vector where the n-th entry in Y is given by mean(X(1:n)). So, Y(end) = mean(X), and Y(1) = X(1). cumvar works in the same way, and this can be done on an arbitrary... Platforms: Matlab

This script achieves exactness by manipulating values stored as a long integer mantissa with an integer exponent (base two). All arithmetic operations are exact except for division which has regular floating point precision. Platforms: Windows, Mac, *nix, Python, BSD Solaris

The correlation function calculated from one realization of an ensemble is inherently flawed since the expectation operation does not come into play. Hence it is important to have an idea of the variance in the correlation function. Platforms: Matlab

FASTRMS Instantaneous root-mean-square (RMS) power via convolution.FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate... Platforms: Matlab

This code determines the mean first passage time (MFPT) of an Ornstein-Uhlenbeck process from analytical solutions obtained from M.U. Thomas (1975), S. Sato (1977), and S. Sato & M. Ricciardi (1988) (all articles published in J. Appl. Prob.).Note that this code yields a dimensionless MFPT (i.e.... Platforms: Matlab

Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides... Platforms: Matlab
