MATLAB: How to display text in a plot as scientific number

MATLABplottext;

How do I display a very small/large number in text command as a number with 2 digits after the decimel point?

e.g. 5.42e-6 rather than 0.00000542 or 5.4200e-06

thanks,

Ziv

Use a format string to create specific format desired...

>> sprintf('%.2e',pi*1E6)
ans =
    '3.14e+06'

ergo, use

text(x,y,sprintf('%.2e',valueToPrint))

There's also num2str, compose that have some additional flexibility for specific uses...

function str =  getstring()
str = input('Enter A String: ','s');
end

Try sprintf:

message = sprintf('Line #1\nThe second line.\nAnd finally a third line.');
plot(1:20);
text(5, 5, message, 'FontSize', 20, 'Color', [.6 .2 .6]);
