Reading vector elements into a string
4 views (last 30 days)

I have a vector of numbers that I would like to use to create a filename. For example with a vector [1] I would like the filename temp0001.file. This is simply done by
filename = sprintf('%04d', vector);
This doesn't carry over once I append more elemnts to the matrix, for example [1,2] should result in temp0012.file but instead becomes temp0102.file. Is there another way to parse the vectors?

temp = sprintf('%d', [0 0 0 0, vector]);
temp = temp(end-3:end);
filename = sprintf('temp%s.file', temp);

filename = sprintf('temp%04d.file', sum(vector .* 10.^(length(vector)-1:-1:0)));

n = [1 2] ; % your vector
v = sprintf('%.0f' , n) ; % convert n to char
filename = sprintf('%04d',str2num(v));
