Return the Einstein product of the input. The Einstein product of two real scalars x and y is: (x * y) / (2 - (x + y - x * y))
For one vector argument, apply the Einstein product to all of the elements of the vector. (The Einstein product is associative.) For one two-dimensional matrix argument, return a vector of the Einstein product of each column.
For two vectors or matrices of identical dimensions, or for one scalar and one vector or matrix argument, return the pair-wise Einstein product.
