MATLAB: Am I unable to open the System Identification App in Matlab R2014b

systemidentification

The error I receive upon clicking the System Identification icon under the "Apps" tab is as follows – Undefined function or variable name 'systemIdentification'. The system identification toolbox is installed and I have checked this using the 'ver' command.

Installed and present with ver does not guarantee that you have it licensed. What do you see if you use

which -all systemIdentification

Note: the systemIdentification app was introduced in R2014b, the version you indicate; if you were accidentally running an earlier version then the function would not be available.

MATLAB: What is changing in R2014b

Hi Chad,

First, one of the purposes of the prerelease is to provide you with an opportunity to test your code against up and coming changes as well as to provide feedback on what went well and what didn't. It's too bad you can't install the prerelease :(

Second, Star is right that the prerelease comes with an NDA so we can't talk about it. But I can answer your second question which is release agnostic. You can use verLessThan to make decisions about what code path to take. If for any release you need a switch mechanism (new features to take advantage of, incompatibilities, etc.) you can use this as the criterion

if verLessThan('matlab','8.4')
 % <=R2014a 
 do_something
else
 % >R2014a
 do_something_cooler
end

Hope this helps.

PS. It's hot down here in Texas!

MATLAB: Older versions of MATLAB available with Home license

I believe I have seen people with Home license mention downloading older version.

I have not found out for sure whether 32 bit versions can be downloaded for the license, but as the package was created no later than R2015a, I believe you should be able to download R2015a and R2015b. What I have not been able to determine is whether you can download versions from before Mathworks created the Home license.
