在 Ipython 输出中写入 Latex

Question

考虑 IPython 笔记本中的以下行：

 B=1.0e5   # in Gauss
 fce = 1.80e6 * B
 print "Electron gyrofrequency $f_{ce}$= %0.5e " %(fce)

我无法让 $f_{ce}$ 以乳胶形式打印。我也试过：

     from IPython.display import display, Math, Latex 
     display ("Electron gyrofrequency" + Math(r'f_{ce}') + "= %0.5e " %(fce))

我收到一个错误：

 TypeError: cannot concatenate 'str' and 'Math' objects

Answer 1

您可以通过将其传递给 Latex 构造函数来呈现完整的乳胶字符串：

from IPython.display import Latex

B=1.0e5   # in Gauss
fce = 1.80e6 * B 

Latex("Electron gyrofrequency $f_{ce}$= %0.5e " % fce)
