I have a matrix 
    A=[  39       77516      13     2174         0       40
      50       83311      13      0           0       13
      38      215646      9       0           0       40
      53       234721      7       0           0       40
      28      338409       13      0           0       40]
i replace some values using
for i=1:5
    for j=1:6
            if (A(i,j)>17&&A(i,j)<=18.5)
                A(i,j)=0.111;
            end  
             if (A(i,j)>18.5&&A(i,j)<=20.5)
                A(i,j)=0.112;
             end 
               if (A(i,j)>20.5&&A(i,j)<=30)
                A(i,j)=0.113;
               end
                if (A(i,j)>30&&A(i,j)<=40.5)
                A(i,j)=0.114;
                end
                if (A(i,j)>40.5&&A(i,j)<=48)
                A(i,j)=0.115;
                end
                if (A(i,j)>48&&A(i,j)<=54.5)
                A(i,j)=0.116;
                end
    end
    end
I get output as
1.0e+005 *
        0.0000    0.7752    0.0001    0.0217         0    0.0000
