How to extract matrix elements corresponding to a logical matrix?

Suppose I've a matrix A - (204 x 245) which has values (0-3) at certain locations. Value 2 is located in this matrix in the shape of a rectangle (see attached image). I want to extract the portion of MATRIX where 2 appears. First I tried using logical indexing which generates correct logical matrix (containing 0/1), let's call it 'P'. When I pass that logical matrix (P) as an argument to the original matrix (A), it gives me a (double) matrix of order (80X1). I wanted the output (of order: 8 x 10 as apparent in figure) in the form of (double) matrix, not as vector.

P = A == 2;             % Logical indexing (output: 204 x 245)
Q = A(P);               % Gives vector off type double (80 x 1)

% Required?
% A(37:44 , 76:85)

I also tried find() to extract row & column indices but still couldn't get the required matrix. Perhaps I'm doing something wrong :( Kindly guide me in this regard.

P.S: The coding is dynamic so a solution like A(37:44 , 76:85) is useless

Answer 1

P=(A==2);

Q=A(any(P,2), any(P,1))

Thank u v much! That's what I wanted. I was missing any() function

Answer 2

[Matt J]

[I,J]=find(A==2);

Q=A(min(I):max(I),  min(J):max(J));

Thanks Matt ! This one also works fine :)
