Python acosh示例

示例#1

文件： spineTilingEngine.py 项目： unhyperbolic/verilen

def length_from_matrix(m):
     t = m.trace()
     if t.real().center() < 0:
         # Trace only determined up to sign
         # We prefer the one with positive real part because
         # SageMath's acosh has undesirable branching behavior.
         t = -t

     return 2 * acosh(t / 2)
