hello i named the rows of a table as follows

MT={'A','B','C','D','E'};

the other elements in the table are [S,Rd,Ratio,doi,kd] i want to display the MT at max(s), this is the code i used

for i=1:x
  kd(i)=input('perm of damaged zone: ');
doi(i)=input('depth of invasion: ');
rd(i)=doi(i)+rw';
  s(i)=((ko/kd(i))-1)*(log(rd(i)/rw))';
Rd=[rd]';
  S=[s]';
  ji=log(re/rw);
  jd(i)=log(re/rw);
  jo(i)=(log(re/rw))+(s(i));
  R(i)=jd(i)/jo(i);
  Ratio=[R]';
table(S,Rd,Ratio,doi,kd,'RowName',MT)

t = table(S,Rd,Ratio,doi,kd,'RowName',MT);
[~, maxrow] = max(t.S);  %get row index of max
maxrowname = t.Properties.RowNames(maxrow) %get string corresponding to row index
