MATLAB: How to vectorize each digit of an integer and store it as an array

arraysbasicsintegersMATLAB

I have to convert an integer into a vector of all its digits. Example: 100—> [1 0 0]
function ans = int2vec(x)
t=regexp(num2str(x),'\d','match');
[];
arrayfun(@(i) [ans,str2num(t{i})],1:length(t));
end
Though this worked for me, is there a better solution.

Best Answer

>> num2str(100)-'0'
ans =
   1   0   0
If you want all digits, regardless of position and role (e.g. exponent):
>> s = num2str(100);
>> s(isstrprop(s,'digit'))-'0'
ans =
   1   0   0
