How to dialte a binary matrix?

I want to dilate a binary matrix (containing 0 and 1). So if I have a matrix 10x10 Note that dilation is all 4 sides (row left, row right, column left and column right). The Output matrix should be of the same size.

if true
A=
1  1  1  1  1  1  1  1  1
1  0  0  0  1  1  0  0  1
1  0  0  0  1  1  0  0  1
1  0  0  0  0  0  0  0  1
1  0  0  0  0  0  0  0  1
1  0  0  0  0  0  0  0  1
1  0  0  1  1  0  0  0  1
1  0  0  0  0  0  0  0  1
1  0  0  0  0  0  0  0  1
1  1  1  1  1  1  1  1  1
% i need this
B=
1  1  1  1  1  1  1  1  1
1  1  1  1  1  1  1  1  1
1  1  0  1  1  1  1  1  1
1  1  0  1  1  1  1  1  1
1  1  0  0  0  0  0  1  1
1  1  1  1  1  1  0  1  1
1  1  1  1  1  1  0  1  1
1  1  1  1  1  1  0  1  1
1  1  1  1  1  1  1  1  1
1  1  1  1  1  1  1  1  1
or this
B=
1  1  1  1  1  1  1  1  1
1  1  1  1  1  1  1  1  1
1  1  0  1  1  1  1  1  1
1  1  0  0  1  1  0  1  1
1  1  0  0  0  0  0  1  1
1  1  0  1  1  0  0  1  1
1  1  1  1  1  1  0  1  1
1  1  1  1  1  1  0  1  1
1  1  0  1  1  0  1  1  1
1  1  1  1  1  1  1  1  1

Use imdilate()

B = imdilate(A, ones(3));
