Measured

UTC time (universal time convention) is used in ANSI-C standard for defining time. This is measured in seconds since 1970, at the Prime Meridian.The UTC2Datenum_array function takes a M x 1 array of UTC time values and converts it to a M x 1 array of Matlab serial Time values.This code is derived...

Hidden Markov models are used to describe the "stepping" behavior of molecular motors, as measured by single-molecule fluorescence techniques. Our HMM implementation is more versatile than the one described by Milescu, et al. Biophys. J. 91:3135-3150 and can be used as a "blind" step detector or...

This demo uses sound to identify the location of an object. The listening array is two microphones, which will allow us to estimate the position along the straight line between the microphones. Location estimation is based solely on the rms value of the noise measured at the two microphones. Note...

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).This...

zpkfit uses the nonlinear least-squares fitter (lsqnonlin) to fit an analytic model of any (fixed) number of poles and zeroes to numerical (presumably measured) frequency response data. It takes as arguments a frequency vector, a frequency response vector, and vectors of the initial guesses of...

This Function HistConnect will make a smooth histogram for a signal or image consisting of a few samples. The function assumes correlation between the samples, and implicitly generates new linear-interpolated samples between the originate samples. Thus makes the assumption of continuity between...

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must...

This function can be used to perform multiple comparisons between groups of sample data.The Bonferroni correction is used to keep the total chance of erroneously reporting a difference below some ALPHA value.For example, consider an experiment with four patients. Their temperature is measured at...

This is set of functions that allow opening of Molecular Imaging atomic force microscope files into Matlab matrix. Unzip the files in one directory and type in Matlab command prompt:y=ReadSTP('pathfilename.stp',buffer number).Matrix y will contain z values of measured surface. Comments will show...

The geometric double-entity model method (GDEM) is proposed to gives far-near degrees between clusters (namely, GE distances), which integrate the absolute distance between nearest sample sets and the dense degrees of border regions of two clusters. GE distances are measured based on the...

In a one-way analysis of variance random effects model one would expect that the measurements lie close together because the same quantity was measured and states that the class effects stem from a common source and therefore should not difer too much. In the random model some variation is...
