The function gets the 2nd derivatives of a vector with two finite boundaries The function gets the 2nd derivatives of a vector with two finite boundaries.
function V2ndDx = get_V2ndDx(V,delta_x,INDstart,INDend)
Input: V = the input vector, 1D data delta_x = delta x INDstart = first index INDend = last index
Output: V2ndDx = 2nd derivative of M with respect to x (horizontal direction)
This is a simple utility to detect EPSPs, IPSPs, EPSCs, or IPSCs in a data set with many adjustable parameters if necessary. It is based on a cumulative derivative function on a smoothed version of the data. A graphical interface to the function...

This is a prediction market (AKA event derivative or idea future) module for Drupal. It is currently not completely functional. The development of this module is being done completely in the open as a learning tool as part of the Drupal Dojo. See...
We present here a program Fie that solves numerically Fredholm integral equations of the second kind on an interval [a,b] to a specified, modest accuracy. Test programs are also included for the various cases. The program TestAll, with no input...
A kalman filter based on a constant velocity model and constant process noise reaches is steady-state after few samples. In steady-state the actual position estimate of the kalman gives the same performances of a zero+two-pole lowpass filter...
The two inputs X and Y are vectors defining a set of N points. The function uses Lagrange's method to find the N-1th order polynomial that passes through all these points, and returns in P the N coefficients defining that polynomial. Then,...
