I am trying to export a matrix into a text file. The text file will later be feed into another program that requires all variables in a specific columns have the same starting location, and the same length.
How should I achieve this? Which Matlab function should I use to export the data?
Thank you.

use sprintf formating, such as
a=rand(5,1);
sprintf('%20.2f\n',a(:));
doc sprintf
It also applies to fprintf.

No, sprintf() and fprintf() will repeat the format as often as needed to write out all the data.

What do you mean? What exact format do you want to achieve? Please read through the document of sprintf formatting. I think it should be able to cover most if not all format.
Is this what you need?
sprintf('%010.2f\n',45,-45,26.7,126.8)
