xscale.signal.fitting.sinval

xscale.signal.fitting.sinval(modes, coord)

Evaluate a sinusoidal function based on a modal decomposition. Each mode is defined by a period, an amplitude and a phase. This function may usually be used after a sinusoidal fit using xscale.signal.fitting.sinfit().

Parameters:

modes : xarray.Dataset

A dataset where the amplitude and phase are stored for each mode

coord : xarray.Coordinates

A coordinate array at which the sine functions are evaluated

Returns:

res : xarray.DataArray
