YilmIndexVector
Compute the index of an 1D array of spherical harmonic coefficients corresponding to i
, l
, and m
.
Usage
index
= pyshtools.YilmIndexVector (i
, l
, m
)
Returns
index
: integer- Index of an 1D array of spherical harmonic coefficients corresponding to
i
,l
, andm
.
Parameters
i
: integer- 1 corresponds to the cosine coefficient
cilm[0,:,:]
, and 2 corresponds to the sine coefficientcilm[1,:,:]
. l
: integer- The spherical harmonic degree.
m
: integer- The angular order.
Description
YilmIndexVector
will calculate the index of a 1D vector of spherical harmonic coefficients corresponding to degree l
, angular order m
and i
(1 = cosine, 2 = sine). The index is given by l**2+(i-1)*l+m
.
