A contour of a 2D region is defined by an ordered set of points where the neighboring elements contain the neighboring points. Such representation can be obtained with many techniques such as boundary tracing and chain codes. (In a simple 2D point set or a curve the points do not have to lie in a specific order.)
The contour smoothing is done by projecting all the contour points onto the local regression line. For each point, N...

ToleranceFactor computes the exact tolerance factor k for the two-sided (optionally also for the one-sided) p-content and gamma-confidence tolerance interval TI = [Xmean - k * S, Xmean + k * S], where Xmean = mean(X), S = std(X), X =...
Nonlinear state estimation is a challenge problem. The well-known Kalman Filter is only suitable for linear systems. The Extended Kalman Filter (EKF) has become a standarded formulation for nonlinear state estimation. However, it may cause...
Two methods are provided - 1) an automatic updation method which can be effectively used outside of a loop since it writes out a newton-raphson computation file from the parameters received. 2) a manual file generation method; effective...
The Hodrick Prescott Filter (HP-Filter) is the most popular method to separate a time series x_t into its components. Let's suppose that the original series is composed of a trend component g_t and a cyclical component c_t. Solving the...
