# OuterProduct

Module that calculates the outer product of its two input vectors. The outer product is a matrix of size s1*s2, where s1 is the size of the first input and s2 is the size of the second input. Each element in the output matrix is the product of one element i each of the inputs: output[j][i] = input1[j]*input2[i]. If the inputs will be flattened before the elements are multiplied if they are not one-dimensional . The output is thus always a two-dimensional matrix regardless of the dimensions of the inputs. The outer product is also somtimes called the tensor product.
