本教程舉例說明了如何使用 ADO 編程模型對數(shù)據(jù)源進行查詢及更新。教程首先講述了完成此項任務(wù)的必要步驟,然后分別通過 Microsoft Visual Basic、以 VC++ Extensions 為特征的 Microsoft Visual C++、Microsoft Visual Basic、Scripting Edition 和以 ADO for Windows Foundation Classes (ADO/WFC) 為特征的 Microsoft Visual J++ 進行更為具體的說明。

基于VB的遺傳算法軟件實現(xiàn) 在程序中,FitnessValue (i) 為適應(yīng)度值數(shù)組、avFit2nessValue (100) 為歸一化適應(yīng)度值數(shù)組、Population2 Chrom(i ,j) 為遺傳個體的等位基因值、Popsize 為種群中的個體數(shù),CHROMLENGTH為一母體對的等位基因 總數(shù)。

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).

function [U,V,num_it]=fcm(U0,X) % MATLAB (Version 4.1) Source Code (Routine fcm was written by Richard J. % Hathaway on June 21, 1994.) The fuzzification constant % m = 2, and the stopping criterion for successive partitions is epsilon =??????. %*******Modified 9/15/04 to have epsilon = 0.00001 and fix univariate bug******** % Purpose:The function fcm attempts to find a useful clustering of the % objects represented by the object data in X using the initial partition in U0.
