示例1: _ff2chi
# 需要导入模块: from larch import Group [as 别名]
# 或者: from larch.Group import chi [as 别名]
def _ff2chi(pathlist, group=None, paramgroup=None, _larch=None,
k=None, kmax=None, kstep=0.05, **kws):
"""sum chi(k) for a list of FeffPath Groups.
Parameters:
------------
pathlist: a list of FeffPath Groups
paramgroup: a Parameter Group for calculating Path Parameters [None]
kmax: maximum k value for chi calculation [20].
kstep: step in k value for chi calculation [0.05].
k: explicit array of k values to calculate chi.
Returns:
---------
group contain arrays for k and chi
This essentially calls path2chi() for each of the paths in the
pathlist and writes the resulting arrays to group.k and group.chi.
