[GDI-Bitmap] 3dtrans DL : 0: 3D Transforms Demonstration Program. Requires Turbo C Version 1.5. Project file should contain the line DEMO3D.C GRAPHICS.LIB 3D.LIB DRIVERS.LIB The library directory must include 3D.LIB and GRAPHICS.LIB, and the include directory must include 3D.H. DRIVERS.LIB must be created by converting the .BGI files to .OBJ files (using the BGIOBJ utility in Turbo C version 1.5) and collecting them in a library (using TLIB). The program displays a cube, a tetrahedron, and an octahedron in three dimensions. Each figure is rotated about a different axis.

[matlab] PLSUVECV DL : 0: PRINCIPLE: The UVE algorithm detects and eliminates from a PLS model (including from 1 to A components) those variables that do not carry any relevant information to model Y. The criterion used to trace the un-informative variables is the reliability of the regression coefficients: c_j=mean(b_j)/std(b_j), obtained by jackknifing. The cutoff level, below which c_j is considered to be too small, indicating that the variable j should be removed, is estimated using a matrix of random variables.The predictive power of PLS models built on the retained variables only is evaluated over all 1-a dimensions =(yielding RMSECVnew).

[Fractal program] fractaldim(y-Q-M) DL : 0: 计盒分形维数计算的matlab源代码编程实现过程-Function [Fdgen NoisfreFD ]=fractaldim(y,Q,M) __________________________________________________________________________ Usage: Computes fractal dimension by box counting(BC) method. NOTE: Running the code may take a little time, because it calculates dimensions for all embedding dimensions up to M. This code is based on an algorithm that constructs a box for the first observation and for other observations test which it belongs to previous box(s). If the observation belongs to one of the existent boxes then increases number of points in the relevant box,otherwise makes a new box. the algorithm of this code uses only rounding down and it does not need binary coding, sorting and so on. It uses only transformation data to [0,2^32-1] and finding valid boxes based on Leibovich and Toth(1989). Inputs: y is a vector time series. q stands for generalized dimension q=1 entropy dimension,q=2 correlation dimension and so on. q=0 is box counting dimen
