Cross product

`C = cross( A,B)` returns
the cross product of

If

`A`and`B`are vectors, then they must have a length of 3.If

`A`and`B`are matrices or multidimensional arrays, then they must have the same size. In this case, the`cross`function treats`A`and`B`as collections of three-element vectors. The function calculates the cross product of corresponding vectors along the first array dimension whose size equals 3.
