Composition

Usage

Composition[ ,  ,  , ... ] 表示函数  ,  ,  , ... 的复合。


Notes

Composition 允许构建以后用于特殊参数的函数的复合。
• 例如: Composition[a, b, c][x]LongRightArrow .
• 可能的话,包含IdentityInverseFunction[f]Composition对象被自动求值。
Composition 有属性 FlatOneIdentity.
a @ b @ c 给出 a[b[c]].
a // b // c 给出 c[b[a]].
• 参见Mathematica全书: 2.2.9.
• 同时参见: Nest, Function.
Further Examples

This generates a function that is the composition of these three trigonometric functions.

In[1]:=  

Out[1]=

You can use this function to evaluate symbolic and numeric quantities.

In[2]:=  

Out[2]=

In[3]:=  

Out[3]=
