This may sound like a silly question but I need to get MatLab to format real number output to three (3) decimal places. I know format bank will do two (2) decimal places and the format short G or format shortg will do decimal places to five (5) deceimal places but I only need three (3). Is there a way to get MatLab to do that?

The round function has several options, however using it will change how the numbers are represented internally, not only how they are displayed.
It might be most appropriate to usse sprintf with the '%.3f' format descriptor to do what you want.

Been using the round option but sometimes it woudl force a whole number as round deals primarily with integers. However, noticed where that was happeneing, I was missing a ")" or a "," in the line.
I also force alot of my output into a .txt files using the fprintf function, then reload as needed later. This forces MatLab to use the numbers in the format it is given. I also do this to create a record of what was produced (helps a lot with debugging). Just wish it didn't slow down the script the way it does.
Thanks for your input, will use it in the areas where the information generated is not output first. Looks like this came down to syntax again.
