cupy.interp#

cupy.interp(x, xp, fp, left=None, right=None, period=None)[source]#

One-dimensional linear interpolation.

Parameters:

x (cupy.ndarray) – a 1D array of points on which the interpolation is performed.
xp (cupy.ndarray) – a 1D array of points on which the function values (fp) are known.
fp (cupy.ndarray) – a 1D array containing the function values at the the points xp.
left (float or complex) – value to return if x < xp[0]. Default is fp[0].
right (float or complex) – value to return if x > xp[-1]. Default is fp[-1].
period (None or float) – a period for the x-coordinates. Parameters left and right are ignored if period is specified. Default is None.

Returns:

The interpolated values, same shape as x.

Return type:

cupy.ndarray

Note

This function may synchronize if left or right is not already on the device.
