How do I delete rows and columns from a matrix

I know this has been asked before, but I am new to matlab and all the answers I read through were jargon to me. So if someone could really dumb this down that would be wonderful. That being said, I have a simple matrix A= [1 2 3; 4 5 6; 7 8 9]. If I want to make A1 = the same matrix with the second row deleted and A2 = matrix A with the second column deleted. How would I do this? I can delete the end rows and columns, but can not seem to figure out a way to delete middle sections. Again, I know this has been asked so I appreciate your patients. Thanks in advance.

A= [1 2 3; 4 5 6; 7 8 9];

A1=A;

A1(2,:)=[];

A2=A;

A2(:,2)=[];

A1 , A2

DONE!!!

Here are a couple different ways to do each:

A= [1 2 3; 4 5 6; 7 8 9];

A1 = A([1 3],:);

A1 = A;
A1(2,:) = [];

A2 = A(:, [1 3]);

A2 = A;
A2(:,2) = [];

The first method in each selects all but the second row or column, and the second method in each sets a specific row or column to ‘empty’ or ‘[]’. There are likely other methods as well, but those are the ones that come quickly to mind tonight.

Thank you for your help. This actually makes sense!
