i saved my output in txt file.....
myOutput = Image Processing is interesting
i wanted to display the word "Process" in green color and the remaining words in black color itself....
i found a link in which we can format the text in different ways....
but in all those examples we give the full text to change color... but i want only a portion of the text to change its color...
if found the starting position of Process and the position upto which i want to change color... but i dont know how to keep the other text colors black and "Process" only green...... please can someone help me solve it.... i need the output to be displayed either in command window or txt file.... but the only thing is the change in color shud be there.....please do reply....

Use a combination of FPRINTF and CPRINTF, without outputting CR/LF before the "final" end of line.
>> fprintf('This is a ') ; cprintf('_red', 'colorful ') ; fprintf('example!\n') ;
but be aware that CPRINTF is rather slow.
>> tic ; for k = 1:1e2, fprintf('.') ; end ; fprintf('\n') ; toc
....................... ..
Elapsed time is 0.001758 seconds.
>> tic ; for k = 1:1e2, cprintf('_red', '.') ; end ; fprintf('\n') ; toc
....................... ..
Elapsed time is 1.458687 seconds.

I know this isn't what you want, but in case others want to know how to "burn" colored text into images, see this link : http://www.mathworks.com/matlabcentral/fileexchange/38721-embed-text-and-graphics-in-an-image
