openExample('signal/LinearChirpExample') is unidentified in version 2015. Help

Shouldnt Matlab automatically 'see' the current version and translate automatically the command to avoid 2 hours of hassle????

With respect to openExample, see https://www.mathworks.com/matlabcentral/answers/276377-why-want-the-code-generation-examples-open#answer_215823

"Shouldnt Matlab automatically 'see' the current version and translate automatically the command to avoid 2 hours of hassle????"

No, it should not do that. That would add an undue layer of complexity and time delay, that every time an unknown function was encountered, MATLAB would have to check some server to determine whether there had ever been a known function of that name and would have to match the data types of the parameters and suggest the rewriting.

For example, in the early hours of this morning, I renamed one of my logical vectors, but missed changing it in one place. My vector was named tf. I quickly discovered the problem because I happen to have the Control System Toolbox installed and it took the inputs and created a Transfer Function object that then crashed the code. But if I did not happen to have Control System Toolbox installed, then under your proposal, MATLAB should have communicated with a server, found tf in that toolbox, noticed that I do not have the toolbox, noticed that I do have the Symbolic Toolbox, and so under your proposal it should have suggested writing my intended logical vector into a series of statements involving sym() and ilaplace(). That would have been... confusing.

I couldnt figure out the answer so I download 2016, but to find out the example 'openExample('phased/MatchedFilteringOfLinearFMWaveformExample')" does not even exist in the example folders. How do I find it on the matworks website?

When you see a example in the current release, you can search your release to see if the same thing is there.

The page to search archived documentation is http://www.mathworks.com/help/doc-archives.html

In R2016b, the example is at https://www.mathworks.com/help/phased/ug/matched-filtering.html

The corresponding archived R2015b page is https://www.mathworks.com/help/releases/R2015b/phased/ug/matched-filtering.html which has pretty much the same content but just does not have the example stored in a convenient script.

Hi, Walter Roberson,

excuse me, I cannot open the simulink example by using this command --

openExample('simulink_automotive/BuildingAClutchLockUpModelExample'),

the error is

Error using findExample (line 46)

Invalid argument "BuildingAClutchLockUp".

could you please help with this problem?

Thanks.

Best regards

Ting, Liang

[Walter Roberson]

That appears to be R2020b and later command. For R2020a use

sldemo_clutch

[Ting Liang]

oh, I see, I can open it now with your new command.

Man thanks.
