I will provide a very naive method here. Maybe someone has a better solution.
H = {[],[],5,[],3}; % original array
for i = 1:size(H,1) % loop through rows (1)
for j = 1:size(H,2) % loop through columns (5)
if isempty(H{i,j})
H{i,j} = [0]; % if empty, replace the empty array with zero
end
end
end
H_new = cell2mat(H) % convert cell to matrix
You could use a temporary cell array if you do not want to modify the original cell array H.
