Exponential Fourier Series

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... Platforms: Matlab

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... Platforms: Matlab

This block implements the PID control equations found on page 1680 of the Foxboro I/A Series Integrated Control Block Descriptions Manual Volume 3, dated May 31 2006. Use this block when the target platform for a PID control design is a Foxboro I/A Series DCS.These blocks have been field verified... Platforms: Matlab

Two tanks in are disposed in series. The level of tank 2 must be controlled despite a sine wave disturbance in the flow F3. This is achieved by changing the flow rate F0 of liquid to tank 1. The tanks areas are A1 and A2. Flow equations depends on constants K1 and K2. A proportional control with... Platforms: Matlab

When drawing financial time series from various markets, one usually needs to make some adjustments before evaluating the series. One of the major concerns is that due to different national holidays or working days across countries, the dates happen to be not synchronized. Clearly this could make... Platforms: Matlab

4 files are included in the package:(1) fs01.m - the 1st-order local linear approximation (LLA) very similar to algorithm by Farmer and Sidorowich (1987). Uses constrained linear least squares (lsqlin) and(2) ts1.m - to reconstruct the vectors of the state space.(3) Example.m - runs fs01 and ts1... Platforms: Matlab

This package shows how to compute the sum of some very strange convergent series.The harmonic series 1/1 + 1/2 + 1/3 + ... + 1/n + ... diverges. This means that the sum can be made as large as desired by adding enough terms.Suppose we delete from this series all terms with a "9" in the... Platforms: Matlab
