共轭梯度法，是数值分析中很重要的一种，源码为其在matlab中的实现。(Conjugate gradient method, numerical analysis is a very important one in the matlab source code for its realization.)

利用CFD软件，采用雷诺应力模型分别计算了300型和250型水力旋流除砂器的内流 场，得到了2种水力旋流除砂器的轴向、径向、切向速度及压强的分布曲线。通过对所得结果的 分析，发现模拟结果基本符合旋流除砂器的运行规律。比较2种旋流除砂器的内流场，表明改进 的300型水力旋流除砂器的结构及分离能力优于原来250型水力旋流除砂器，为水力旋流除砂器 的优化设计和选型提供了可靠的设计依据。(use CFD software, Reynolds stress model used to calculate the respective 300-and 250-type sander hydrocyclones the flow field, been two kinds of hydrocyclones sander axial, radial and tangential velocity and pressure in the distribution curve. Based on the results of the analysis, the simulation results are consistent with the Cyclone sander operating rules. Comparing two kinds of Cyclone sander within the flow field, show improved 300 Desanding Hydrocyclones the structure and separation capacity than the original 250-hydrocyclone sander, Desanding Hydrocyclones for the optimum design and selection provided a reliable basis for the design.)

程序为参数寻优的集合，包含当今主流优化工具，适合初学者参考。(Program for the parameter optimization of collection, including today s mainstream optimization tool, suitable for beginners reference. )

给出了关于图像的多种处理方法，并且自己相处了想出了分水岭算法的改进(Given a variety of approaches to image processing, and got along with the idea of an improved watershed algorithm)

说明：  这是一个matlab科学计算的初步实验。对初学matlab的人有一定的帮助(This is a preliminary experiment matlab scientific computing. Matlab for beginners who have some help)

实现FFT谱分析，并进行全相位FFT谱与传统FFT谱的比较(To achieve FFT spectrum analysis, and comparison of all phase FFT spectrum with the traditional FFT spectrum)

输入自己事先录制好的语音信号，该程序实现将语音信号通过FIR低通、高通、带通滤波器后还原出来的语音质量(Enter their own pre-recorded speech signal, the program will realize voice signal through the FIR low-pass, high pass, band-pass filter to restore them after the voice quality)

牛人自己编写的基于morlet小波的连续小波变换，可以修改其中参数，但是输出与matlab自带的函数有出入，在修正中。(Prepared by the cattle themselves morlet wavelet continuous wavelet transform, where the parameters can be modified, but the output function that comes with matlab discrepancy in the amendment.)
