FFT

说明：  带数据的经济调度方案，只包含火电厂，没有其他能源。(he economic dispatching scheme with data only includes thermal power plants, without other energy sources.)

数字进制转换：输入任意一个十进制数，能转换成二进制和十六进制。(Digital hex conversion: enter any decimal number，and they can be converted into binary and hexadecimal.)

改变图像的灰度级数，通过输入的数值确定灰度级(change degree of gray )

用MATLAB辅助设计IIR数字滤波器.pdf 非常详细，值得参考！！！(good！！！！！)

基本原理就是首先求解出连续系统微分方程的近似解，然后对系统的Jacobian矩阵进行QR分解，计算Jacobian矩阵特征值的乘积，最后计算出LE和分数维(The basic principle is to first find the approximate solution of differential equations continuous system, then the system will be on the Jacobian matrix QR decomposition product Jacobian matrix computing eigenvalues, and finally calculate the fractal dimension LE)
