# When was the function introduced?2

Posted by Jiro Doke,

Working at MathWorks, I have become spoiled and have become used to always having access to the newest release (actually, I have access to future releases under development). When I was an application engineer delivering seminars, I would get questions like “when did that command become available?” or “I just tried to run it on my MATLAB and I get an error”.

For functions introduced after R2006a, I would show the documentation, as it shows when a function was introduced.

Reza’s entry gives you this information directly at the command line.

when filloutliers

## [filloutliers] is a Matlab function or an ordinary m-file (Introduced in R2017a).


Very nice idea! I have one suggestion for improvement. The code only searches for MATLAB or Simulink functions. It would be great if it can search any toolbox functions.

Give it a try and let us know what you think here or leave a comment for Reza.
