MATLAB: Force a scientific notation format

plotting

hi,
when i use this code, instead of forcing it to give me the x-axis as: 0,1,2,…,10 then x10^3 (3 is a superscript) it gives me the numbers as 1000,2000,…and so on…any idea?
    x = 0:0.1e4:0.1e5;
y = randn(11,1);
plot(x,y,'b-o')
set(gca,'xtick',0:0.1e4:0.1e5);

Best Answer

 x = 0:0.1e4:0.1e5; 
 y = randn(11,1); 
 plot(x,y,'b-o')
 xVals = 0:0.1e4:0.1e5;
 set(gca,'xtick',xVals);
 set(gca,'XTickLabel',sprintf('%2.0e|',xVals));
The last line in the previous snippet sets the format for your XTickLabels. For more information on other formats:
 doc sprintf
EDIT Exponent should appear at the right of the X-axis
 x = 0:0.1e4:0.1e5; 
 y = randn(11,1); 
 plot(x,y,'b-o')
 xVals = 0:0.1e4:0.1e5;
 set(gca,'xtick',xVals);
 expVal = 3; %exponent you want
 set(gca,'XTickLabel',sprintf('%2.0f|',xVals./(10^expVal)));
 pos = get(gca,'Position');
 offset = 0.00; %how far to the right you want the exponent
