我们学校的c实验教程非常详细，需要的可以下载试用。希望大家喜欢-C experiment of our school curriculum is very detailed and need to download the trial. I hope everyone likes

哈哈通用C语言函数-Haha common C language function

说明：  比如有图像1，将其旋转n度得到图像2，问如何比较两张图像得到旋转的度数n。(to calculate the angle between two pictures)

一些常用的小函数-some frequently used small function

ansys 用于分析纤维增强复合材料的专用模块ACP。非常好的内部培训资料。(ansys fiber reinforced composites for analysis of specific modules ACP. Very good internal training materials.)

一些用3DMax软件建好的建筑物模型，可供大家实验使用。-err

通过matlab计算图像的谱内相关性和谱间相关性(The intra spectral correlation and spectral correlation are compared)

结合案例来描述每一种统计学模型，解释如何开展数据分析，讨论采用模拟手段来检验模型，这是模型开发与评估中的重要方面，给出多层回归模型（如多层ANOVA、多层线性回归和广义多层模型），指导如何用R语言采实现诸多方法，在线提供书中所用到的数据集和R语言脚本。(Combined with the case to describe each kind of statistical model, how to carry out data analysis and interpretation, discusses the use of simulation to test the model, this is an important aspect of the development and evaluation of the model, given the multi regression model (such as multilayer ANOVA, multi linear regression and generalized multi model), how to achieve a lot of mining method with the R language guide online provide the data set and the R script used in the book.)

Bouc-wen模型python程序，考虑了12个参数，没有考虑刚度退化。(Bouc-wen model python program. Twelve parameters are considered, and stiffness degradation is not considered.)
