- second input array. Must be compatible with `x1` (see {ref}`broadcasting`). Should have a numeric data type.

- axis over which to compute the dot product. Must be an integer on the interval `[-N, N)`, where `N` is the rank (number of dimensions) of the shape determined according to {ref}`broadcasting`. If specified as a negative integer, the function must determine the axis along which to compute the dot product by counting backward from the last dimension (where `-1` refers to the last dimension). If `None`, the function must compute the dot product over the last axis. Default: `None`.
