How can I proceed? I tried like this but "Undefined operator '~=' for input arguments of type 'cell'" :

teste2 = teste1;

if teste2(:)~=0

teste2(:)='V';

elseif teste2(:) == 0

mask = strcmp(catracio1, 'low') & strcmp(catpreco, 'low');

teste2(mask) = {'1'};

mask = strcmp(catracio1, 'medium low') & strcmp(catpreco, 'medium low');

teste2(mask) = {'2'};

mask = strcmp(catracio1, 'medium') & strcmp(catpreco, 'medium');

teste2(mask) = {'3'};

mask = strcmp(catracio1, 'medium high') & strcmp(catpreco, 'medium high');

teste2(mask) = {'4'};

mask = strcmp(catracio1, 'high') & strcmp(catpreco, 'high');

teste2(mask) = {'5'};

else

teste2(:)=0;

end

I think the problem is in these lines:

if teste2(:)~=0

teste2(:)='V';

but I get really confused about what you want to do:

1. isempty(teste2);%determine whether teste2 is empty

2. teste2{1} ~= 0;%determine whether the first cell element of teste2 is zero

I hope this will help;

You need to answer the questions I asked you in your earlier post of the same question:

What are you data structures here? Is it that case that for every teste1 entry, teste1(K), that there is a corresponding catricio1{K} and corresponding catpreco{K} entry? And is it correct that for the locations where test1(K) is 0, you want to compare the two corresponding string entries and if they are equal then you want to assign a character corresponding to the class number to teste2{K} ? And is it the case that if the two strings are not equal, or the two strings are something other than one of those 5, that you want to assign '0' to teste2{K} ? But where test1(K) was non-zero you want to assign 'V' to teste2{K} ?
