Compare strings which contains the same pattern by ignoring case sensitivity and some expressions like underscores
You might remove those expressions to be ignored and unify the strings all to lowercase before doing actual comarison.

非线性微分方程
>> s = dsolve(eqn,cond) 警告: Unable to find symbolic solution. 没有精确解。 这没什么奇怪的，一个一般的微分方程大概率没有精确解。

我的MATLAB使用不了滑动条，应该是缺少uislider函数，但是不知道怎么修补
uislider是R2016a推出的函数，你是不是MATLAB版本太老？ 如果版本没问题就是安装损坏了，卸载MATLAB重装吧

错误使用 sprintf 无法将 'matlab.ui.Figure' 值转换为 'int64'
gcf是当前图窗Figure对象，又不是一个数值，怎么可能用sprintf当作数值输出呢？你要输出图像编号的话就得手动指定一个数值编号
