飞思卡尔实现PID算法

雷劈数，或名卡布列克数，定义为：若正整数X（在n进位下）的平方可以分割为二个数字，而这二个数字相加后恰等于X，那么X就是（n进位下的）卡布列克数。例如55^2=3025，而30+25=55。   印度数学家卡普列加（Dattaraya Ramchandra Kaprekar, 1905 - 1986）在一次旅行中，遇到猛烈的暴风雨，他看到路边一块牌子被劈成了两半，一半上写着30，另一半写着25。这

这是数据挖掘中的一次作业，用推荐系统的方法，来对电影打分。SVD(Singular Value Decomposition)的想法是根据已有的评分情况，分析出评分者对各个因子的喜好程度以及电影包含各个因子的程度，最后再反过来根据分析结果预测评分。

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
