im getting close but need some help. code worked for last 2 columns but not for first couple. gave me multiple of what looked like max and min number from them. i posted the command window underneath with what its outputting. Again, i need the max value in each column without using built in functions.

A=randi(100,6,5)
for column=1:5
   columns=A( :,column)
   cmax=-inf;
 for row=1:6
     rows=columns(row, :);
     if rows>cmax
         cmax=rows;
      
     end
     disp(cmax)
       end
       
end
A =
     9    49    53    37    10
    27    58    24    99    27
    81    24    49     4    34
     3    46    63    89    68
    93    97    68    92    14
