MATLAB最优化问题中的armijo线搜索算法

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

这个是斯坦福大学在coursera 公开课上的机器学习的练习2的习题答案和原题。仅供参考。 有在学习机器学习的同学，可以选择andew_ng在coursera 公开课上的机器学习，这是一个很好的课程，而且算法讲的很详细，这个代码是里面练习的参考答案之一，对于刚开始学习的同学很有用。
