@outer
Syntax: @outer(v1, v2)
Argument 1: vector, rowvector, or series, v1
Argument 2: vector, rowvector, or series, v2
Return: matrix
Calculates the cross product of v1 and v2. Vectors may be either row or column vectors. The outer product is the product of v1 (treated as a column vector) and v2 (treated as a row vector), and is a square matrix of every possible product of the elements of the two inputs. Example:
matrix m1=@outer(v1,v2)
matrix m4=@outer(r1,r2)
