Using fprintf, how to print 1.234D+02 instead of 1.234E+02?

I'd like to print scientific notations into a file, in the format of FORTRAN. For example, I want to print 1.234D+02 instead of 1.234E+02 into the file. How to realize it? Thank you all~

fprintf only supports e or E.

You will have to either replace the characters after writing the file, or use sprintf and replace the characters before writing the file.

Thank you~ Trying sprintf

EDIT

As said before, Stephen's answer is the way to go and I had previously posted an erroneous answer. Second try:

mag = @(x) floor(log10(abs(x)));
val = @(x) x./10.^mag(x);

x = [-25, -0.0001, 0, 0.00025, 1.005, 15, 12345];

leftVal = val(x);
leftVal(isnan(leftVal)) = 0;
rightVal =  mag(x);
rightVal(rightVal == -Inf | rightVal == Inf) = 0;

sprintf('%.3fD%+03d\n',[leftVal;rightVal])

Than you~~

If you are going to construct a string, then why not just use sprintf() along with

S(S == 'e') = 'd';
S(S == 'E') = 'D';

Thank you for your advice, I want to print numbers

[Walter Roberson]

S = sprintf('%.3e',YourNumber)
S(S=='e') = 'D' ;
