matlab code 3 dim using fimite differance time domain method

说明：  运用最小二乘法对传感器进行了建模和反建模，可以对其补偿(The least square method of modeling the sensor and anti-model, can be compensated for its)

MemoArray文件夹下是两个组件，可以安装到BCB的组件面板中，用于在C++中方便输入输出。(MemoArray folder are two components can be installed to the BCB Palette for the input and output.)

Multiwavelet wavelet theory has become a hot one, it is more than wavelet function and a number of scaling function to indicate signal. [1] using fractal interpolation function is the first of a multi-wavelet, as GHM Multiwavelets.

说明：  此程序是运用music方法估计功率谱，并实现了信号还原。(This program adopts the mathod of music psd to estimate the powerdensity,and get the original signal.)
