I have tried using Diary, but it does not store line number. Nor does it store the command after which the error is captured. I need to understand how to write a logger properly in MATLAB, so I could add messages as well along with capturing error.

@Atin: you can find a few logger tools here:

I have also written functions to make this easier, but which are not present on the file exchange yet. I'm currently on mobile so I can't attach them. You can find an old version in this thread.

As per my understanding you wanted a logger that helps you to record errors ,warnings and success messages of a function file.

You can use log4m for logging your matlab code . Log4m is designed to be relatively fast and very easy to use. It has been designed to work well in a matlab environment. Use this documentation to learn more about log4m -
