Hi all, I am trying to convert a categorical array to a cell array so that I can use the strrep function, but i cant seem to find anyway to do it after scouring the web to the best of my abilities. My categorical column contains string that have the '_' character and i want to search the column and replace any string that has '_' with '-'. Is there any way I can do it without converting the datatype? Any help would be greatly appreciated. Thank you

a=nominal({'R_','G_','B_'});
b=cellstr(a);
c=strrep(b,'_','-');
d=nominal(c)
d =
R- G- B-

@Fangjun Jiang update new workflow.
a=categorical({'R_','G_','B_'});
b=string(a);
c=replace(b,'_','-');
d=categorical(c)
BTW, Convert categorical array to cell array in general way Example.
A = categorical(["A","B","C","D","hello","world"]) % categorical array
dst = num2cell(A) % cell array
if A is a complex arrays,also can use mat2cell function.
A = categorical(["A","B","Hello","world .";
"1","2","3","四"])
dst = mat2cell(A,[1,1],[2,1,1])
