摘要:符号运算时有些多项式的系数值接近于0,像这样 fun = 3.5753839759325595498222646101085e-49*x + 1.8367099231598242312011508394098e-40*y - 3.1684752276643959044089436923507e-34 + 555*z + 4*x*y 需要将其直接消掉,化简成这样 fun = 555*z + ...

摘要:假如我们编写了一个积分通用程序,想使它更具有通用性,那么可以把被积函数也作为一个参数。在c/c++中,可以使用函数指针来实现上边的功能,在matlab中如何实现呢?使用函数句柄——这时类似于函数指针的一项功能。假如我们现在已经编写了一个辛普森方法积分的函数如下,我们要把函数作为参数传给它(当然啦,matlab早已经提供给我们非常牛x的积分函数了,这里只是个例子而已): function g=myi...
