How do you add a 0 in front of single digit numbers in a numerical array?

I later want to convert 2 numerical arrays into a string array and then back to a numerical array to combine a series of numbers. HOWEVER - to do this the numbers need to have the same amount of integers otherwise I get an empty matrix.
So my question is, how would I tell matlab to put a 0 in front a singular numbers in a 1x56 numerical array so all the numbers have the same amount of digits?

There is no such thing as leading zeros when it comes to numerical variables. Leading zeros in the string variable will vanish when "put that into a numerical".
Try to formulate your question/problem in other words.

num2str, fprintf and sprintf all have options to specify a format when converting a numeric value to a string.
a=num2cell(1:10);
b=cellfun(@(x) sprintf('%02d',x),a,'UniformOutput',false);
