A module for diff geo
Project description
difdyf
calculate differential geometry content
difdyf 是一个计算不同度规场，坐标系下各种张量的库
更多功能正在添加中
使用方式
import difdyf as df
g,symb=sphereMetric()## 生成球坐标度规场g，symb=【'r','theta','phi'】
T=getChristSymb(g,symb)## 生成球坐标下克氏算符
R=getRiemannCurvature(T,symb)## 生成球坐标黎曼曲率张量
##输入度规场g可任意指定，需要是一个2维字符串值的字典，例如g['r']['r']='1'
安装
$ pip install difdyf
