MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。-MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab c

针对EMD方法的不足,利用最小二乘法进行拟合多元非线性方程，matlab开发工具箱中的支持向量机。- For lack of EMD, Multivariate least squares fitting method of nonlinear equations, matlab development toolbox support vector machine.
