Dot product of arrays
 in Python - GeeksforGeeks)
In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used. It is often called the inner product (or rarely projection product) of Euclidean space, even though it is not the only inner product that can be defined on Euclidean space (see Inner product space for … Webnumpy.dot #. numpy.dot. #. numpy.dot(a, b, out=None) #.
