VC读写图像的基本程序，可以作为学习数字图像处理的基础。(VC basic procedures to read and write image, digital image processing can be used as the basis for learning.)

The two dimensional LMS program is used to enhanced image contrast by adaptive filtering process, it operates on every fixel through each row and column

直线电机控制仿真，伺服系统中的电流环控制(Linear motor control simulation, the current loop servo control system)

The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.

主分量分析,用于高维数据降维或提取目标特征。程序精简，效率高. (Principal Component Analysis is used to make data dimensionality reduction or extract target characteristics。)

说明：  对故障数据的小波包分解与信号重构、小波包能量特征提取 暨 小波包分解后实现按频率大小分布重新排列，并进行降噪处理。(After wavelet packet decomposition and signal reconstruction, wavelet packet energy feature extraction and wavelet packet decomposition, the fault data can be rearranged according to the frequency distribution, and the noise can be reduced.)

说明：  This function is used by Newton s Method for systems and by Broyden s Method
