如何用R实现 f(x,z)=int_a^b f(x,y,z)dy ?
然后如何实现 f(z)=int_a^b int_c^x f(x,y,z)dydx ?
谢谢 | g******n
发帖数: 339 | 2 For one dimensional integration, R has a function called integrate, but it
is for numerical integration, not for symbolic integration. R also has a
seperate multi-dimensional integration package. According to my experience,
R is not good in numerical interation in terms of ease of use and computing
efficiency compared to maple and matlab.
For symbolic integration, maple is definitely the best choice.
On the other hand, if you insist on doing this kind of thing using R, you
can create a function
