说明：  基于谱减法的语音增强在MATLAB实现源程序(speech enhancement in MATLAB source)

利用霍夫变换的原理，能够实现二值空间的圆检测。获得预期的图像信息。(Using the principle of Hough transform, the value of space to achieve the second round test. Achieve the desired image information.)

基于hht的大地电磁信号资料处理理MATLAB方法实现可直接使用。 (Based on hht magnetotelluric data processing management MATLAB method can be used directly.)

用各种方法求解初值问题微分方程，并分析误差。(Use various methods to solve the initial value problem of differential equation, and the error analysis.)

说明：  使用Matlab对图片进行操作时，大量的单张图片不利于操作，此时需要将图片转化为.mat格式，.mat方便我们对数据的处理，使我们更加高效的利用数据。文章中的代码是以PIE数据集作为转换的原始数据，每张图片的名称是连续的数字，相同类别的图片张数相等且名称连续。(When using MATLAB to operate pictures, a large number of single pictures are not conducive to operation. At this time, we need to convert pictures into. mat format. mat is convenient for us to process data, so that we can use data more efficiently. The code in this article is PIE data set as the original data for conversion. The name of each picture is a continuous number. The number of pictures of the same category is equal and the name is continuous.)
