I want to plot some result which shows how different is the model A from model B etc. My error is something zero. do you have any idea how I can show that the interpretation would be easy too?

  Err 1  Err2  Err3     Err4  Err5
  A  0.0142   0       0.0410    0     0
  B  0  0  0.0138    0     0
  C  0  0  0         0     0
  D  0  0  0         0     0
  E  0.0142  0      0    0     0
  F  0  0  0         0     0
  G  0  0  0         0     0
  H   0.0135 0   0.0416667 0  0.0138889

I have no idea what you are doing, but the bar3 function might be what you want.

For example:

Xt =   [{'Err1'}  {'Err2'}  {'Err3'}   {'Err4'}  {'Err5'}];
Yt = [{'A'} {'B'} {'C'} {'D'}  {'E'}  {'F'}  {'G'}  {'H'}];
  M = [  0.0142   0       0.0410    0     0
    0  0  0.0138    0     0
    0  0  0         0     0
    0  0  0         0     0
    0.0142  0      0    0     0
    0  0  0         0     0
    0  0  0         0     0
     0.0135 0   0.0416667 0  0.0138889]; 
figure(1)
bar3(M)
set(gca, 'XTickLabel', Xt)
set(gca, 'YTickLabel', Yt)

produces:

You are right.I made mistake I used the previous "set" and then over right the last one. anyway I found the same figure as you did. I have one question before I accept your solution. can you please let me know whether you know how to plot it like following figure? because if you see your plot does not show for the last one (one columns before the last is dominating the other) . do you know how to plot it like attached file ?

The ribbon plot is about as close as we can get. You can change the width of the ribbons and rotate the plot to get the result you want:

[X,Y] = meshgrid(1:8, 1:36);
figure(1)
ribbon(Y, M, 0.1)
set(gca, 'Xtick', 1:8, 'XtickLabel', Xt, 'FontSize',6) 
set (gca, 'YTick', 1:36, 'YtickLabel', Yt, 'FontSize',6)
view([50 50])
