Is it possible to cross 2*1 and 2*1 vectors in matlab I have a case,
A =
-20.5120
92.1404,
B =
3.5051
-3.9759
I have to cross(A,B), help me with your suggestions

In general you would extend the vectors with a zero to make them 3-element vectors. If this is valid in your case is something you'll have to figure out.

As far as I understand your question you have two vectors with, x-component and y-component. Now, in order to use the in-build cross product function, the documentations mentions that you need to have a length of 3.
So if it doesn't affect you, then I too would suggest you to follow the same method that Rik has suggested to use the in-built function.
If not, you can try to generate your own code for the use case with the idea being, If A=[a1;a2]; B=[b1;b2]; then cross product will be C=(a1b2-a2b1); along the perpendicular to both the input vectors.
Hope this helps Cheers!
