mindspore.numpy.unwrap
- mindspore.numpy.unwrap(p, discont=3.141592653589793, axis=- 1)[源代码]
Unwraps by changing deltas between values to
2*pi
complement. Unwraps radian phase p by changing absolute jumps greater than discont to their2*pi
complement along the given axis.说明
For absolute jumps that are within a very close range to pi, unwrapping may be done differently than numpy due to differences in round-off.
- 参数
