svm的回归预测分析，包含源代码和数据，测试可用(svm regression analysis to predict, including source code and data, test available)

介质共形FDTD技术，可以很好地计算圆柱介质的谐振频率，也可以计算谐振腔中含有介质球的谐振频率(Dielectric conformal FDTD technique can be a good medium to calculate the resonant frequency of the cylinder can also calculate the resonant frequency of the resonant cavity containing a dielectric sphere)

《压缩感知及应用》代码，许多常用的学习压缩感知matlab代码(The compression perception and application code, many commonly used compression perception of learning matlab code)

径向基函数插值使用一系列基函数，它们在每个采样点对称且居中。径向基函数是一类特殊的函数，其主要特征是它们的响应与中心点的距离单调地减小（或增加）。中心、距离刻度和精确的形状是模型的参数。(Radial Basis Function interpolation with biharmonic, multiquadric, inverse multiquadric, thin plate spline, and Gaussian basis functions for Matlab/Octave. RBF interpolation uses a series of basis functions that are symmetric and centered at each sampling point. Radial basis functions are a special class of functions with their main feature being that their response decreases (or increases) monotonically with distance from a central point. The center, the distance scale, and the precise shape are parameters of the model.)
