这是一本关于地球物理反演方法的经典著作《Parameter Estimation and Inverse Problems》，学地球物理的可以看看。(this book is for geophysics inverse problem base study. worth reading if you are a student of geophysics.)

this source code is matlab cctime

说明：  %This function finds the cubic splines for the input data points (x,y) %Input: x = [x0 x1 ... xN], y = [y0 y1 ... yN], xi=interpolation points % KC = 1/2 for 1st/2nd derivatives on boundary specified

说明：  本书以MATLAB作为仿真环境，系统地介绍了滑模变结构控制的几种先进的控制方法。本书凝练了作者多年来从事控制系统教学和科研工作的经验，同时融入了国内外同行近年来取得的最新成果。(This book uses MATLAB as the simulation environment to systematically introduce several advanced control methods of sliding mode variable structure control. This book condenses the author's years of experience in teaching and scientific research on control systems, and at the same time incorporates the latest achievements made by domestic and foreign counterparts in recent years.)

光伏并网发电系统中逆变器的研究与设计,比较有用的资料，逆变器设计可以参考(Grid-connected PV system inverter design, useful information, inverter design can refer)

说明：  MATLAB答题卡识别（GUI，论文） 本课题为基于MATLAB的不变矩答题卡识别。可识别学号，学科，答案，并进行分数统计，以及判断是否及格。后台可设置标准excel答案。经过灰度变换形成灰度图像、二值化处理、图像滤波、边缘检测、hough变换等预处理。带GUI交互式界面。(Matlab answer card recognition (GUI, paper) This topic is based on MATLAB moment invariant answer card recognition. Can identify student number, subject, answer, and carry out score statistics, as well as judge whether pass. Standard excel answers can be set in the background. After gray-scale transformation, gray-scale image, binary processing, image filtering, edge detection, Hough transform and other preprocessing are formed. With GUI interactive interface.)

同轴线的计算，内有注释说明同轴线的计算，内有注释说明(Coaxial line calculation, there are comments that the calculation of coaxial line, there are explanatory notes)

采用功率谱方式并用AR线性滤波方法生成脉动风速时程数据，能用于结构风载荷的计算。(Using power spectrum and AR linear filtering method to generate fluctuating wind speed time series data, can be used in structure wind load calculation.)

说明：  通过BP神经网络学习一个3维的函数的源代码，为加快速度，程序初始化的为已经经过学习的得到结点权值，如果预设为随机值，将重新学习。(BP neural network through a three-dimensional study of the function of the source code to speed up, the initialization procedure for the study has already been node weights, if limited to random value, re-learn.)
