How programmatically know if an Update is installed for a particular matlab release?

Hello,

MathWorks proposes some Updates for a given release.

For instance, (at this time writing) there are 4 proposed Updates for R2018b; and 2 ones for R2019a.

I know about this post https://fr.mathworks.com/matlabcentral/answers/102880-how-do-i-check-for-updates-using-matlab

but my question is: does a function such ver or version would explicitely indicate which Update if installed (if any) ?

Regards

Pascal

Answer 1

Yes. See the output of version:

9.6.0.1114505 (R2019a) Update 2

With

ver('Matlab')

you get the version number only. But with

ver

the output of version is displayed.

[James Richard]

Could you do it with windows command line?

On cmd,

matlab -help

has the same output as

ver('Matlab')

but not

ver

Maybe this helps.

[ver datestr] = version

ver =

'9.9.0.1495850 (R2020b) Update 1'

datestr =

'September 30, 2020'

Answer 3

[Jorik Caljouw]

Another way to get this info is with

vd = version('-description')

If no update is installed you get:

vd =

0×0 empty char array

If an update is installed you get (e.g.):

vd =

'Update 7'

There is a new "matlabRelease" function available since R2020b that will directly output the update release number:

>> releaseInfo = matlabRelease

releaseInfo = 

  matlabRelease with properties:

    Release: "R2022b"
      Stage: "release"
     Update: 0
       Date: 24-Aug-2022

[Image Analyst]

s = ver

s = 1x92 struct array with fields:
    Name
    Version
    Release
    Date

for k = 1 : numel(s)
	fprintf('#%d, Using %s, Version %s, Release %s, Date %s\n', ...
		k, s(k).Name, s(k).Version, s(k).Release, s(k).Date);
end

s is a structure with info about base MATLAB and the 91 toolboxes that are installed in this online version. For you it will contain info about however many toolboxes you have. Since I, and online MATLAB, are on the first release of a new version, I don't know yet if it will contain update info, like if you're on update 2 or 3 or whatever of a particular year release.
