# cupy.dot¶

cupy.dot(a, b, out=None)[source]

Returns a dot product of two arrays.

For arrays with more than one axis, it computes the dot product along the last axis of a and the second-to-last axis of b. This is just a matrix product if the both arrays are 2-D. For 1-D arrays, it uses their unique axis as an axis to take dot product over.

Parameters: a (cupy.ndarray) – The left argument. b (cupy.ndarray) – The right argument. out (cupy.ndarray) – Output array. The dot product of a and b. cupy.ndarray
