Changing 'precision' through startup ?

1 view (last 30 days)
Simple question, yet i havent found an answer: Is it possible to set the precission used for output (eg. using dlmwrite) in the startup.m file so i dont have to define it every time i use dlmwrite ?

When you open the dlmwrite function, you will find that the standard value for precn is always 5 (variable precn in subfunction parseinput). Either just set the precision every time or create a "hull function" which passes all inputs further on to dlmwrite and adds the precision as additional parameter:
function dlmwrite2(varargin)
dlmwrite(varargin{:}, 'precision',2);

Be careful. It is NEVER a good idea to edit supplied MATLAB functions, as it is too easy to accidentally edit the code, then not realize you did something and even save the code without thinking. You will create bugs.
So rather than opening code using edit, use the type command to dump it to the command line. Just as easy, and much safer.

Dear John,
thanks for your comment, I wasn't aware of the possibility to use the type function. Of course I agree with you to not edit supplied functions.
Best regards,
