Create single dimensional array from multidimensional matrix

I am new to matlab, so please reply even if the question is trivial

I have multidimensional matrix. Lets matrix is A

A(1,1,:) = [1 2 3] , A(1,2,:) = [4 5 6] , A(1,3,:) = [7 8 9]     size(A) = 1 3 3

I want to create an array out of this matrix. I want to find all the data corresponding to A(1,1,:) in an array. Lets say the array is B

B = [1 2 3]   size(B) = 1 3

How this can be done? I don't want to use loop for this operation. Is there any built in function for this?

Thanks
