Undefined operator '>' for input arguments of type 'cell'. Error in sif (line 374) if (hist(i,1)> a)

for l=1:siz
  hist=rt(l);
  max=[1 hist(1,1)];
  for i=1:36
    a=max(2);
    if (hist(i,1)> a)
      max= [i hist(i,1)];
    end
  end

je peut pas vraiment comprendre pourquoi cette erreur ?

Apparently rt is a cell array containing a cell. Hence need to "use the curlies, Luke!" to dereference the content. Try

if hist{i,1}>a

instead.

NB: However, I strongly suggest to use a different variable name than hist; hist is a builtin Matlab histogram function that you've aliased here...

>> which hist
C:\ML_R2016b\toolbox\matlab\datafun\hist.p
>>

For a more precise answer would need to see result of

whos rt

and

whos hist

to see the actual storage pattern.

j'ai essaye avec votre méthode mais il ya a une autre erreur qui s'affiche malgré que j'ai bien vérifie les boucles et les dimension des matrices Index exceeds matrix dimensions.
