Hey,
I would like to replace numbers (-999) as char with a 0 for all -999 in a specific column.
Thanks already!

Hi,
it sounds as if you have a cell array of strings. In this case
allDatabySubj(strcmp(allDatabySubj, '-999)) = {0};
should do the trick.

It doesn't make any sense and I don't know what was intended by it either but I am guessing it is just poor grammar from non-English native tongue poster...

Thanks! Char means character, sorry. I am getting the following error message:
>> allDatabySubj(allDatabySubj(:,6)==-999,6)=0; ??? Undefined function or method 'eq' for input arguments of type 'cell'.
