Could anyone please help me how to split a single matrix into two separate matrix with odd number of rows and even number of rows

I am having a matrix

A= 20x20 double

From A, I want to split it into two matrices B =20x10 double and C=20x10 double

In specific I used the command

B=A(:,1);
C=A(:,2);

where i can get B=20x1 double and C=20x1 double.

But now I want to get B=A(:,1); (:,3),(:,5),...,(:,19) and C=A(:,2), (:,4), (:,6),...,(:20).

Could anyone please help me on this.
