The array is shifted using spline interpolation of the requested order. Points outside the boundaries of the input are filled according to the given mode. The input array. The shift along the axes. If a float, shift is the same for each axis. If a sequence, shift should contain one value for each axis. WebThe circular shift can be of two types: Left circular shift (moving the final bit to the first position while shifting all other bits to the next position). Right circular shift (moving the first bit to the last position while shifting all other bits to the previous position).
