How to compare two string are equal or not

Hi,

I have two string (names array in cell matrix), and want to compare ith & i-1th name is equal or not.

Names={'Mhajj56_Too';'YHJA_90_Kty';'Mahjkl_uiT00';'Mahjkl_uiT00';'aha';'Mhajj56_Too';'Mhajj56_Too'}
out=[different
       different
       same
       different
       different
     same]

Rule: if ith name is same as i-1th, then we say same, else different.

Many thanks in advance,

A one-liner way is:

outLogical = cellfun(@isequal, Names(1:end-1), Names(2:end))

(Note that what you put is not valid syntax unless same and different are variables, not strings.)

Well the obvious, simplest way is with isequal() in a for loop:

Names={'Mhajj56_Too';'YHJA_90_Kty';'Mahjkl_uiT00';'Mahjkl_uiT00';'aha';'Mhajj56_Too';'Mhajj56_Too'}'
numberOfCells = length(Names)
outLogical = false(1, numberOfCells-1);
for k = 2 : numberOfCells
  if isequal(Names{k}, Names{k-1})
    outCellArray{k-1} = 'Same';
    outLogical(k-1) = true;
  else
    outCellArray{k-1} = 'Different';
  end
end
% Show in command window:
celldisp(outCellArray);
outLogical
