One char vector, fixed length hexadecimal, no spaces:

>> sscanf('d1d2d4cf','%2x')
ans =
   209
   210
   212
   207

One char vector, any length, space characters:

>> sscanf('d1 d2 d4 cf','%x')
ans =
   209
   210
   212
   207

From one cell array, any length char vectors:

>> C = {'1','d2','d4','cf'};
>> sscanf(sprintf('%s\v',C{:}),'%x\v')
ans =
     1
   210
   212
   207

sscanf is much more efficient than dec2hex. +1
