sincinterp¶

sofia_redux.toolkit.interpolate.interpolate.sincinterp(x, y, xout, dampfac=3.25, ksize=21, skipsort=False, cval=nan)[source]¶

Perform a sinc interpolation on a data set

Parameters:

xarray_like of (int or float): (shape1,) The independent values of the data
yarray_like of (int or float): (shape1,) The dependent values of the data
xoutarray_like of (int or float) or (int or float): (shape2,) The new independent values of the data
dampfacint or float, optional: damping factor for sinc interpolation
ksizefloat or int, optional: Kernel size used for interpolation. This should be a positive odd integer. If an even value is passed, then the kernel size will be increased by one. Float values will be floored.
skipsortbool, optional: By default, x and y data are sorted by the x value. This can be a fairly intensive operation, so if you know the data is already sorted, then set skipsort to skip sorting. Note, this is dangerous as no error will be reported. Be sure you have a sorted x before attempting.
cval: float, optional: Value to fill in requested interpolation points outside the data range.

Returns:
