error in replacing values

    I have a matrix 

    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
      0.0000    0.8331    0.0001         0         0    0.0001
      0.0000    2.1565    0.0001         0         0    0.0000
      0.0000    2.3472    0.0001         0         0    0.0000
      0.0000    3.3841    0.0001         0         0    0.0000

1.0e+005 *0.0001 for all values,pleasehelp

Answer 1

[G A]

use format('long') before output and you will see that everything is OK

[G A]

and, instead of for-loop you can use:

A(A>17&A<=18.5)=0.111;

A(A>18&A<=20.5)=0.112;

A(A>20&A<=30)=0.113;

A(A>30&A<=40.5)=0.114;

A(A>40&A<=48)=0.115;

A(A>48&A<=54.5)=0.116;
