文件1 txt,2 txt,3 txt和5 txt为用Fortran编写的有限元程序 4 txt为用c＋＋编写的钢筋混凝土异形柱的全()

说明：  计算导航信号不同调制方式的功率谱，包括bpsk，mboc等调制方式(Calculate the power spectrum of different modulation methods of navigation signal)

在matlab的环境中，使用了当前用于跟踪预测的相关向量机方法对被测对象的失效过程进程进行跟踪评估。(tracking)

Cohen类时频方法采用不同的核函数来抑制交叉项，本质上是在模糊域对信号进行低通滤波，其中典型的方法有Choi-Williams 分布和Cone-shaped 分布等。(The Cohen time frequency method uses different kernel functions to suppress the cross term, which is essentially a low pass filter for the signal in the fuzzy domain. The typical methods are Choi-Williams distribution and Cone-shaped distribution.)

利用matlab实现图像的边界检测。包括sobels算子，prewitt算子，还包括图像的边界追踪(use matlab to detect the boundary of the image)

运用New-Rapshon方法计算线接触常温弹流润滑程序,很好的(The use of New Rapshon method to calculate line contact elastohydrodynamic lubrication under normal temperature program, very good)

近景摄影DLT的L近似值的求解代码 此程序主要应用于桥梁挠度的测量中(The L approximation close range photogrammetry DLT solving code This program is mainly used in the bridge deflection measurement)

简单蚁群算法求解TSP的matlab源程序 不错的源码 很好(A simple ant colony algorithm to solve TSP matlab source good source is very good)

先用PCA降维，在利用支持向量机进行分类，这个分类是二分类，所以PCA的降维降到两维即可分类。(Firstly, PCA dimensionality reduction is used to conduct classification with support vector machine. This classification is binary classification, so the dimensionality reduction of PCA can be reduced to two dimensions for classification.)
