How can I find the version in which a function was introduced?

The release in which a function was introduced can usually be found at the bottom of the documentation page of that function.

Alternatively, if the release needs to be found programmatically, there is a contribution in the file exchange which was developed for this purpose, see the link below,

FEX #54483 does not work, and I'm pretty sure it didn't work at the time of this post (or shortly afterward).

when_original readtable % FEX #54483 does not work

## [readtable] is a Matlab function or an ordinary m-file (No information found).

Fixing it is a fair amount of work, and there are a lot of functions and methods that it simply cannot find because of the way it's written.

when_modified readtable % modified to parse the webpage correctly

## [readtable] is a Matlab function or an ordinary m-file (Introduced in R2013b).

when_modified createMask % but it fails because it tries to guess the url

Connection error or no online documentation found for [createmask].

I posted a version that currently works and has basic improvements.

https://www.mathworks.com/matlabcentral/fileexchange/97272-a-slightly-more-robust-version-of-when

when readtable % FEX #97272 works

## readtable -- Introduced in R2013b

when createMask % and it does a better job

## imroi.createmask -- Introduced in R2008a
## images.roi.assistedfreehand.createmask -- Introduced in R2018b
## dicomcontours.createmask -- Introduced in R2020b
