其余混沌的数字图像置乱。该算法利用混沌对初值的敏感性，算法是想简单。(The rest of Chaos Digital Image Scrambling. The algorithm using the sensitivity of chaos to the initial value, the algorithm is to simple.)

matlab下数字信号处理实现实例，对初学者很说是很好的教材，包括源码实现(digital signal processing under matlab realize examples, for beginners it is good teaching materials, including source code to achieve)

说明：  本程序利用平均周期图法（bartlett法）对信号进行功率谱估计，指定输入响应信号，根据实际情况调整参数，输出功率谱图(The program uses the average periodogram method (bartlett method) on the signal power spectrum estimation, specify the input response signal, adjust the parameters according to actual situation, the output power spectrum)

改进的灰色预测模型,简单实用，可用于经济预测及其他预测问题，预测精度高 (Improved gray prediction model, simple and practical, can be used for economic forecasts and other prediction, forecast accuracy)
