Will work also for non-square input matrix x.

Test	Status	Code Input and Output
1	Pass	x = 1; n=1; y_correct = 1; assert(isequal(stop_zig(x,n),y_correct))
2	Pass	x =[1 2 3; 4 5 6; 7 8 9]; n=3; y_correct = [ 1 2 4 7 5 3]; assert(isequal(stop_zig(x,n),y_correct))
3	Pass	x =[1 2 3; 4 5 6; 7 8 9]; n=-3; y_correct = [ 9 8 6 3 5 7]; assert(isequal(stop_zig(x,n),y_correct))
4	Pass	x =[1 2 3; 4 5 6; 7 8 9]; n=2; y_correct = [ 1 2 4]; assert(isequal(stop_zig(x,n),y_correct))
5	Pass	x =[1 2 3 4; 4 5 6 7; 7 8 9 10; 10 11 12 13]; n=-3; y_correct = [ 13 12 10 7 9 11]; assert(isequal(stop_zig(x,n),y_correct))
