I want to do exactly what is on this question, but instead of having to give a fixed number of left-side zeros, to be able to give the fixed number of digits that the number has to have in total.
For example, if I have the number 32
, and have a length of 4
, the result should be:
0032
But if on contrary I have the number 122
, then only one 0
should be padded:
0122
any ideas on how to achieve this on Matlab efficiently? sprintf
?
You can use string formatting in num2str
as well as in sprintf
:
num2str( 122, '%04d' );
or
sprintf( '%04d', 32 );
