Set the rows you want to delete to null. Example:

MATLAB: Delete the center in an array

‘I want to delete specific elements(3x3 or 2x2 whatever) inside a big array, and convert the rest of this array into a vector.’

That is straightforward:

A = [6  5  2  2  1  9
     4  3  0  1  2  8
     5  5  6  2  1  7
     9  8  0  1  0  6
     4  4  1  1  0  5
     2  1  1  2  3  4];
Lidx = sub2ind(size(A), [3 3; 4 4], [3 3; 4 4]);
Center = A(Lidx)                                            % View Elements
A(Lidx) = [];                                               % Delete Elements, Return Vector
