Here's one possible situation. I'd be a mind reader though if I happened to pick exactly the scenario you were thinking of:
matrix1 = rand(14,13) % Sample data.
matrix2 = zeros(14, 13); % Initialize to all zeros.
% Get 20 random locations to haul over to matrix2.
numberToTransfer = 20
randomLocations = randperm(numel(matrix1), numberToTransfer);
% Transfer them over from matrix1 to the same locations in matrix2.
matrix2(randomLocations) = matrix1(randomLocations)
