How to add a string output to this function?

Is it possible to add an ouptput, which says what operation made the function, to this following function?

function [op] = operation( A,B )
X=[A+B; A-B; A/B; A*B; B-A; B/A;]
Y=X(randperm(6),:)
if Y(1,1)>0 && Y(1,1)==int16(Y(1,1)) 
    op=Y(1,1);
else
    operation(A,B)
end
end

For example,

   EDU>> operation(4,2)
    ans=
         6

The output is 6, wa all knows that the function did 4+2=6, but how to add the output '+' . For example output:

op = 6 s = +

[Azzi Abdelmalek]

function [op,op1] = operation( A,B )
X=[A+B; A-B; A/B; A*B; B-A; B/A;];
o={'plus','minus','div','prod','iminus','idiv'}
ii=randperm(6)
op1=o{ii(1)};
Y=X(ii,:);
if Y(1,1)>0 && Y(1,1)==int16(Y(1,1))
  op=Y(1,1);
else
  [op,op1]=operation(A,B);
end
end

[David Sanchez]

function [op,s] = operation( A,B )

% your code here

s = '+'; % or whatever you want to be the string

Use a switch/case to choose among your options
