How to convert arrays to strings in bulk at the same time similar with the function itoa in C language

Recently, I try to converts numbers into strings in bulk, but I find the function num2str cost a long time if I convert them one by one with the command for.

Take an example in Matlab

A=ones(1e9,1);

for i=1:1e9

x=num2str(A(i));

end

The time it costs is related to the size of A, I want to convert arrays to strings in bulk at the same time so that the cost time has nothing to do with scale.
