混沌时间序列预测工具箱，包括了李雅普诺夫指数、分形纬、嵌入纬以及神经网络预测(chaotic time series forecasting tool kit, including the Lyapunov exponent, fractal-wai, Wei and embedded neural network prediction)

matlab实现傅里叶变换和傅立叶反变换(Implement fft and ifft)

 利用fft()进行快速傅立叶变换，得到频谱，画出正弦函数及其频谱  找出频谱中使得Y轴取最大值时的估计频率记为ft  加入白噪声，绘出信噪比和均方误差的关系曲线 ( using fft () for fast Fourier transformation, spectrum, to draw the sine function and its spectrum  find the spectrum makes the Y-axis maximum value when the estimated frequency is denoted by ft  adding white noise, SNR plot and mean square error curve)

说明：  通过时域转换为频域，在频域中截取低频部分，去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

使用matlab进行矩阵的高斯分解,可以对高阶线性方程进行数值求解(use Matlab for Gaussian decomposition of the matrix, the high-order linear equations were solved numerically)

巴特沃斯滤波器，切比雪夫滤波器，椭圆滤波器设计及比较，同样的设计参数指标，在同一张图中比较三种滤波器的幅频响应波形，并用统计图画出各滤波器所需阶数。(Butterworth filter, Chebyshev filter, elliptic filter design, the same design parameter index, with a figure in the comparison of three filter frequency response waveform, and use statistical picture of the desired order of each filter.)
