OptiVec contains more than 3500 hand-optimized, Assembler-written functions for all floating-point and integer data types from the following fields: 1. Vectorized form of arithmetic operators and math functions. 2. Matrix operations, e.g.: multiplication, inversion, LU decomposition, singular...

Least Square method is common curve fitting approch. But for special some function, the tradiational Least Square method is hard to get enough accurancy dueo to gobal approximation. Moving Least Square(MLS) can fit any differentiable function through local approximation.

SPtrack is a GUI (Graphical User Interface) based program written in Matlab which is used for tracking single particles and finding Diffusion properties. It works on Matlab 6 and above platforms and requires the Image Processing Toolbox and the Curve fitting Toolbox (optional). The program...
