function of dascore.proc.resample source

    patch: Patch ,
    kind: str | int[str, int] = linear,
    **kwargs ,
)-> ‘PatchType’

Set coordinates of patch along a dimension using interpolation.


Parameter Description
patch The patch object to which interpolation is applied.
kind The type of interpolation. See Notes for more details.
If a string, the following are supported:
linear - linear interpolation between a pair of points.
nearest - use the nearest sample for interpolation.
If an int, it specifies the order of spline to use. EG 1 is a linear
spline, 2 is quadratic, 3 is cubic, etc.
**kwargs Used to specify dimension and interpolation values. Use a value of
None to “snap” coordinate to evenly sampled points along coordinate.

This function just uses scipy’s interp1d function under the hood. See scipy.interpolate.interp1d for information.
