MATLAB: How to format integer numbers to start with filling zeros

digitformatintegernumberprintfstringzero

I would like to transform n = 1:12 to '01','02',…,'11','12'

This only makes context in terms of strings, in which case sprintf makes this easy:

>> sprintf('%02d ',1:12)
ans = 01 02 03 04 05 06 07 08 09 10 11 12

And if you want them in a cell array just use strsplit on it, or cellstr.

If C is your cell array, then

C = regexprep(C,'00/00/00','')

 index = find(A(1,:) == 14);
 A = cat(1,A,zeros(1,size(A,2)));
 A(2,index) = 14;

Added after Sean's point -- if the integer is not present in the row, you'll just get a row of zeros.

   index = find(A(1,:) == 59);
   A = cat(1,A,zeros(1,size(A,2)));
   A(2,index) = 59;
