save output of command window to text files in real time

Hello,

diary command allow to save the output of command window to text file, but it is only updated when the codes stops its execution. What I want is a way to save the outputs as they are appearing in the command window... Is it possible?

Somewhere around R2013a-ish, diary was changed to flush after every line. Unfortunately I cannot seem to find a release note or posting about this so I cannot say exactly when it happened.

Start MATLAB with the -logfile option.

Ok, but that will save the entire session, I just want to save a particular code...

To display in the command window but not save, simply leave the semicolon off the end of the line of code.

To save something whenever you want, you can use fprintf() to write to either a file or the command window, however it's not automatic - you have to put each of the fprintf() lines into your program.

yup, this is what i have so far, but command windows outputs are not saved...
