本程序主要实现了离散时间的傅立叶变换，具有很强的可移值性，原理简单。...

自己写的一个Bayes分类器的matlab程序，比较简单。 使用方法 >> [ train_x, train_y ] = readdata("train_data.txt" ); >> [ test_x, test_y ] = readdata("test_data.txt" ); >> [mode]=MyBayes_train( train_x, train_y); >> [ acurracy, predict_y]=MyBayes_test( test_x, test_y, mode);

乌拉比创立的微波电磁散射模型，主要用于电磁波在植被覆盖区域的计算，用于高大植被覆盖区，将植被分成树冠，树干和地面三个部分，分别计算电磁散射，是目前最经典精度最高的电磁散射模型。

Displays a rotatable and scaleable wire frame of any 3D mathematical function. This can be made up from the normal VB maths plus inverse and hyperbolic functions. Functions can be created and saved as wanted. Image vertices can also be saved for use elsewhere. The MS ScriptControl Eval function simplifies calculations enormously and its use is demonstrated. Also shown are MoveToEx, LineTo which are much faster than the VB equivalents and very easy to use. Included are a set of string handling subroutines such as count characters, squeeze out spaces, replace sub-strings etc. Commented throughout including the 3D maths and perspective methods. All the files are visible and the program is written for an 800x600 screen.
