中文说明：正确率可以达到98％，多元数据分析的主分量分析投影，这是第二能量熵的matlab代码，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，用于图像处理的独立分量分析，音频信号通过LM386放大。
English Description：
The correct rate can reach 98%, multivariate data analysis principal component projection analysis. This is the second energy entropy matlab code, realized by using SDRAM operation NIOS, also with SRAM save camera data, for image processing of independent component analysis, audio signals through the LM386 amplifier.
