C++经典数值算法源码(good)-C classical numerical algorithm source code (good)

This a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functions. The code consists of three simple classes: 1) Calc - which does the main calculations, 2) Stack - which is used to push and pop intermediate operators and numbers and 3) Symbol Table. The symbol table is a collection of calc symbols, a type structure consisting of various elements, including the expression name, function name, and the final value of the expression The evaluation procedure is done in three steps: 1) simplify the expression by removing all the elements within () and storing them in subexpressions within the symbol table. 2) Each of these sub expressions are then converted to RPN format (Reverse polar notation) and evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functi

应用背景 It approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.关键技术This is achieved by relying on integral images for image convolutions; by building on the strengths of the leading existing detectors and descriptors (in casu, using a Hessian matrix-based measure for the detector, and a distribution-based descriptor); and by simplifying these methods to the essential. 

基于bayesian的判别分析应用,可以用于分类、评估等项目，如电信套餐业务评估、旅游推荐系统设计等

計算最近點和線段三個部分。第一部分，生成點後查詢最近點(需要注意根目錄下有Temp.txt)。第二部分，生成N個固定範圍的隨機點(在根目錄下生成latlon.txt)。第三部分，原來生成的一個點和生成的一個線段進行判斷垂足。
