Hi,
I want to calculate the crossproduct (from set theory, not vectorspace
crossproduct) of two vectors x,y.
My method is as follows:
>>> x = array([1,2,3])
>>> y = array([4,5])
>>> xx, yy = meshgrid(x,y)
>>> array(zip(xx.flatten(), yy.flatten()))
array([[1, 4],
[2, 4],
[3, 4],
[1, 5],
[2, 5],
[3, 5]])
I guess there is an easier way to achieve this. Any hints ?
Greetings, Uwe
