for loop return answer in string matrix

I have Ci in dimension (61x3)

and I want the ans in each row

example ans(1,1) True ans(1,2) True ans(1,3) True

This is code that I write

Ci       = [Ca Cb Cc] ;

for i = 1:length(Ci),
    for j = 1:3
        if Ci(i,j)>0
            a = 'True';
        else 
            a = 'False';
        end
        fprintf ('ans %d,%d = %s\n',i,j,a);
    end
end

Thank you for answer

Ci   = randn(5, 4);
pool = ["False", "True"];
a    = pool((Ci > 0) + 1)

a = 5×4 string array
    "False"    "True"     "True"     "True" 
    "True"     "True"     "True"     "False"
    "True"     "False"    "True"     "False"
    "False"    "False"    "True"     "True" 
    "False"    "False"    "False"    "True"
