DIPimage version

[AndreZeug]

Is there an easy way to find the version of DIPimage / DIPlib used in MATLAB?
Since I move from 2.9 to 3.4.1, I need to update a lot of functions. To make it compatible to both versions I would like to find an easy way to identify the version of DIPimage of the running instance to use something like

if myDipVer >=3
  int99 = percentile(dip_image(B), 99));
  ...
else
  int99 = double(dip_percentile(B, [], 99, []));
  ...
end

but I only found (not recommended)
myDipVer = ver('DIPimage'); myDipVer = str2double(myDipVer.Version(1:3))
to get the version of DIPimage.
Is there a recommended way?

Using ver('DIPimage') is a good approach. The only problem with str2double(myDipVer.Version(1:3)) is that this will stop working for version 3.10. I would consider looking only at the first character, see if it's a 2 or a 3.

strsplit(ver('DIPimage').Version,'.') returns a cell array {'major', 'minor', 'patch'}.

cellfun(@str2double,strsplit(ver('DIPimage').Version,'.')) returns a regular numeric array [major, minor, patch].

[Note that the syntax ver('DIPimage').Version works only in fairly recent MATLAB versions, for older versions you need to assign the output of ver() to a variable before you can do the dot indexing.]

You could also do something like exist('dip_percentile','file') when choosing to call dip_percentile vs percentile (though percentile also worked in 2.9), or exist('dip_initialize','file') for a more generic "is this DIPimage v2 or v3?".
