hi, I have problem to find out crossproduct of two vectors(AXB), where each component of vector represent 4X4 matrix
example:
A=[A1 A2 A3]; B=[B1 B2 B3];
where A1 A2 A3,B1 B2 B3 represents 4X4 matrix
thanks in advance

A = randi(18,4,4,3);
B = randi(10,4,4,3); %The initial arrays with size (4x4x3)
out1 = cellfun(@(x,y)cross(x,y),num2cell(reshape(A,[],3),2),num2cell(reshape(B,[],3),2),'un',0);
out = reshape(cat(1,out1{:}),size(A));
