There are two possible workarounds:
1) You can set the Y-ticklabels explicity as follows:
x = [ 1 2 3 ];
y = [10000 20000 30000];
plot(x,y)
set(gca,'YTick',y)
set(gca,'XTick',x)
Yvalues = get(gca,'YTick');
set(gca,'YTickLabel',Yvalues);
2) You could also use the SPRINTF function to format your tick labels using the format of your choice. The 'XTickLabel' or 'YTickLabel' property of the axis would then use those strings as tick labels.
x=[1 2 3];
y=[10000 20000 30000];
plot(x,y)
set(gca,'XTickLabel',sprintf('%3.1f|',x))
set(gca,'XTick',x)
set(gca,'YTickLabel',sprintf('%4.1e|',y))
set(gca,'YTick',y)
For more information on the available formats, consult the documentation for the SPRINTF function:
