I have a double variable named `myData' that contains zero entries. I loop through the elements of myData as follows.

How can I print out the zeros as empty character for a tex file that I am producing?

% Current code
myData=([1,2,0;0,5,6;7,0,9]);
nCol    = 4;
format = '%.2f';
for i = 1:size(data,1) % 1 to rows
    if i==1
        fprintf([' \\\\ \\midrule \\multicolumn{' num2str(nCol) '}{l}{\\bfseries m}  \\\\ \\midrule  \\\\ \n']);
    end
    fprintf([num2str(i)    ' & ' num2str(myData(i,1), format)...
        ' & ' num2str(myData(i,2), format) ...
        ' & ' num2str(myData(i,3), format) '\\\\ \n']);    
end
 \\ \midrule \multicolumn{4}{l}{\bfseries m}  \\ \midrule  \\ 
1 & 1.00 & 2.00 & 0.00\\ 
2 & 0.00 & 5.00 & 6.00\\ 
3 & 7.00 & 0.00 & 9.00\\ 

I don't want to see zeros in the ouputs above. The desired outputs:

\\ \midrule \multicolumn{4}{l}{\bfseries m} \\ \midrule \\

1 & 1.00 & 2.00 & \\

2 & & 5.00 & 6.00\\

3 & 7.00 & & 9.00\\
