How to take cross product of two 2D vector fields

I have 2 vector fields say and . I want to calculate cross product of A and B . I have 2D matrices of and .

i.e.

clear; clc;

% A = (Ax, Ay); B = (Bx, By);

Ax = rand(10,10);
Ay = rand(10,10);
Bx = rand(10,10);
By = rand(10,10);

% how to calculate A X B = ?
