反距离加权法估算降水量时是根据距离衰减规律, 对样本点的空间距离进行加权, 当权重等于1 时, 是线性距离衰减插值 当权重> 1 时, 是非线性距离衰减插值(Inverse Distance Weighting，IDW))

Periodic Noise Reduction by Frequency Domain Filtering

说明：  利用FFT频谱，包络谱，以及谱峭选频滤波的方法，在时间线下诊断故障。(Using FFT spectrum, envelope spectrum, and spectral selection filtering method, fault diagnosis under the timeline.)

此为广义预测控制的一个程序，对象是CARIMA模型。(This is the generalized predictive control of a program, which is aimed CARIMA model.)

简单的卡尔曼程序，里面详细介绍了5条核心公式的使用，适合初学者，里面的注释也很多。(Simple Kalman procedure, which details the use of the five core formula, suitable for beginners, inside comment.)

Begginer Guide to gain understand matlab at the entry level

说明：  里面有很多matlab的源代码，可以用于一套的数据处理。包括样本划分，光谱的预处理等(There are a lot of matlab source code, can be used for a set of data processing.Including sample division, spectral pretreatment and so on)

基于简化的PCNN去除脉冲噪声的matlab算法(Based on a simplified PCNN algorithm to remove impulse noise matlab)

说明：  matlab couse band very very low, butter, butord, chevychebs etc etcmatlab couse band

两种控制方式的性能比较:模糊控制与PID控制(two ways to control the performance comparison : fuzzy control and PID control)
