示例1: _ff2chi

# 需要导入模块: from larch import Group [as 别名]
# 或者: from larch.Group import k [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.
