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\\

s=sprintf([num2str(i) ' & ' num2str(myData(i,1), format)...
' & ' num2str(myData(i,2), format) ...
' & ' num2str(myData(i,3), format) '\\\\ \n']);
fprintf(regexprep(s,'0.00',''));

Thanks so much @David Hill !
It saved enormous time to organise the outputs!
