Among the basic arithmetic operations over finite fields, the computation of multiplicative inverse is the most time consuming operation.
在有限域的基本运算中，乘法逆元的计算是最费时间的运算。
It is not advisable to attempt to write your own normalize, dot, inverse, SQRT operations, however. If you use the built-in ones then the driver will generate much better code for you.
不建议您自己写normalize, dot, inverse, sqrt等操作函数，如果您使用内建函数，底层驱动将会为你生成更好质量的代码。
