C语言源程序解决的-C language source solution

图像分类提取特征时所用的sift算法，具有尺度，旋转，缩放不变性，很好的概述了特征，可以和其他算法结合使用用于图像的分类。

#包括；

大数类，重载了各类操作符，可以直接使用-fate categories, a variety of heavy-duty operator can be used directly

用fortran语言编写的程序，这样可以在fortran系统中直接运行，为大家提供点方便。-using FORTRAN language of the procedure so in FORTRAN operating system directly, to provide a convenient point.

关于c方面的新书大家-on the book everyone a good look! !

采用NLJ随机搜索的方法辨识一个以状态方法表示的非线性系统。选其初值 a1(0) =50 , a2(0) =100 , a3(0) =100 , a4(0) =50 , a5(0) =10 , 选范围为 r(1)(i)=0.5 a(0)(i) , 取数据长度 L ＝40, t =0.005 , 性能指标 J＝ 。迭代计算结果得 a 的估计值 1=17.6043243, 1=17.5977, 2=72.9573, 3=51.3014, 4=22.9889, 5=5.99965, J = 0.000000916 。-Using NLJ random search method to identify a method that the state of the nonlinear system. Election of its initial value a1 (0) = 50, a2 (0) = 100, a3 (0) = 100, a4 (0) = 50, a5 (0) = 10, choose the range of r (1) (i) = 0.5 a (0) (i), check data length L = 40, t = 0.005, performance index J =. Iterative calculation results have a estimated value of 1 = 17.6043243, 1 = 17.5977, 2 = 72.9573, 3 = 51.3014, 4 = 22.9889, 5 = 5.99965, J = 0.000000916.
