欧拉法解常微分方程的MATLAB程序M文件。与大家分享(Euler method for solving the M-file of Ordinary Differential Equations MATLAB program. To share with you)

利用表达式求解和栈的只是，设计一个简易的数学题库， 可供小学生作业，并能给出分数。 要求：建立试题库文件，随机产生 n 个题目；题目涉及加减乘除，带括弧的混合运算；随时可以退出；保留历史分数，能回顾历史，给出与历史分数比较后的评价。(Use solving expressions and stack just design a simple math exam, students for the job, and can give a score. Requirements: Create test file, randomly generating n topics topics involving addition, subtraction with parentheses mixing operation ready to quit keep historical scores, can look back at history, and history is given uation scores after comparison.)

说明：  输入任意数学四则运算表达式可以得出结果,很方便很实用的一个程序的源代码。(you can get the answer.)
