shxarray.exp.multiply

shxarray.exp.multiply.multiply(dash1: DataArray, dash2: DataArray, engine='shtns') → DataArray

Multiply two spherical harmonics DataArrays together (equivalent to multiplying in the spatial domain) Currently this function uses a spherical harmonic synthesis followed, a multiplication in the spatial domain and a spherical harmonic analysis A future implementation may use the realGaunt coefficients to directly erform the multiplication in the spectral domain :param dash1: :type dash1: xr.DataArray :param dash2: :type dash2: xr.DataArray :param engine: Engine to use for the synthesis and analysis step :type engine: str

Return type:

xr.DataArray
