Numpy's ediff1d(~) method computes the difference between each value and its adjacent value in the input array.

Parameters

1. a | array-like

The input array. Multi-dimensional arrays will be flattened to a 1D array.

2. to_end | array-like | optional

The values to append to the returned differences.

3. to_begin | array-like | optional

The values to prepend to the returned differences.

Return value

A Numpy array that contains the difference between each value and its adjacent value in the input array.

Examples

Basic usage

a = np.array([1, 3, 8, 15, 30])
np.ediffd(a)
array([ 2, 5, 7, 15])

Prepending and appending values

a = np.array([1, 3, 8, 15, 30])
np.ediffd(a, to_begin=-5, to_end=9)
array([-5, 2, 5, 7, 15, 9])
