Here's a clunky solution:
function [A] = FillEmptyRows( A )
while 1
emptyCells = cellfun(@(x) isempty(x), A);
emptyRows = all(emptyCells,2);
if ~any(emptyRows)
break;
end
nextRows = circshift(emptyRows,1);
A(emptyRows,:) = A(nextRows,:);
end
end
It works by identifying rows that are entirely empty (so a row with only one empty entry won't be replaced), and replaces that with the next row.
For simplicity, I use circshift to use the logical index on the next row, but that means if your last row is empty it will be replaced by the first row.
If you have multiple consecutive empty rows, the loop will go round several times but you'll always end up with a filled result. Don't call it if EVERY row is empty.
