hi, when i exécute this function an error message appears: Error using get_block (line 9) Not enough input arguments.!!!!!!
function block = get_block( Mat1, block_number )
% returns block of matrix
% 1: Mat2(1:2,1:3)
% 2: Mat2(1:2,4:6)
% 3: Mat2(3:4,1:3)
% 4: Mat2(3:4,4:6)
%
switch block_number
case 1
block = Mat1(1:2,1:3);
case 2
block = Mat1(1:2,4:6);
case 3
block = Mat1(3:4,1:3);
case 4
block = Mat1(3:4,4:6);
otherwise
error('Matrix only has 4 blocks')
end
end

Note that another implementation of your function would be:
function block = get_block(Mat1, block_number)
assert(size(Mat1) == [4, 6], 'Invalid matrix size');
blocks = mat2cell(Mat1, [2 2], [3 3])'; %split matrix into blocks and transpose since indexing is row major
block = blocks(block_number);
end
