extract sub matrix of sub matrix directly

I have matrix a m-by-n-by-p.

b=a(:,:,1) is a sub matrix of a.

I want to extract sub matrix of b (say c) so that

c=b(1:4, 1:4)

Can I extract c from matrix a such as

c=[a(:,:,1)](1:4, 1:4) This means

c=b(1:4, 1:4)

With regards -Abhijit

Yes,

C = a(1:4,1:4,1);

You will have to use reshape if you take a sub-set a different way, e.g.:

>> a = rand(3,3,3);
>> b = a(1:2,1:2,1)

b =

    0.3922    0.7060
    0.6555    0.0318

>> b = a(1:2,1,1:2)

b(:,:,1) =

    0.3922
    0.6555

b(:,:,2) =

    0.6948
    0.3171

>> b = reshape(a(1:2,1,1:2),[2,2])

b =

    0.3922    0.6948
    0.6555    0.3171
