How to write a Logger in MATLAB to record errors, warnings and success messages of a function file?

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.

How are you hoping to use the information from the logger that you want to write? What's your end goal?

Hi Steven, The end goal is to have a log for every execution of the application with timestamp, input Parameter info, error & success Messages with line no. To have a simple log file. Something like Log4j but for Matlab.

@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 -
