zpkfit 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... Platforms: Matlab

Revised Simplex Method. This function is able to detect almost all types of properties/characteristics present in an LPP such as unbounded solution, alternate optima, degenaracy/cycling and infeasibilty. It only fails to work when there are redundant constraints present in the problem. However, it is rare and can be... Platforms: Matlab

FAST CONVEX HULL ALGORITHM Even if totally m-coded, this routine is particularly fast in computing convex hull of 2D points. In many cases seems to be much faster than the matlab library routine. The main reason is that, differently from convhull, this algorithm jumps the call to unique function which can be very slow for... Platforms: Matlab

Mean First Passage Time of an Ornstein-Uhlenbeck Process 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
