说明：   遗传算法的功能，需要下载的赶快啊哈，这个是非常有用的？？(Genetic algorithm, it needs to download quickly Aha, this is a very useful? ?)

混凝土的抗压强度随养护时间的延长而增加，现将一批混凝土作成12个试块，记录了养护日期x（日）及抗压强度y（kg/cm2）的数据：求型回归方程 示例方程在内(The compressive strength of concrete with curing time and increase the extension, now make a number of concrete block 12, recording the date of the conservation of x (day) and compressive strength of y (kg/cm2) of data: the regression equation for sample-based equation, including)

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)

产生2ASK、4ASK、8ASK的m文件和产生的mat格式的数据文件。(Generated 2ASK, 4ASK, 8ASK of m documents and produced mat format data files.)

给出了一个线性调频信号的Gabor变换，使用的是过抽样，其中参数q=4.(given a chirp signal Gabor transform, is the excessive use of sampling, which parameter q = 4.)

用matalab实现一个简单的输入语音的整体信噪比和部分信噪比的比较(Matalab implemented using a simple input speech and the portion of the overall signal to noise ratio SNR comparison)
