I can't save a PSAT file

Hi,

When I try to save a model an error pops up "Too many output arguments." & I can't save the file anyway. Could you please suggest any workaround to fix this?

Thanks

Please post the complete error message including traceback.

I had same problem few days back.But here is the solution, the PSAT is compatible upto MATLAB 2019a only, and I had MATLAB 2020 on my laptop so it didnt work as expected. Later on I installed MATLAB 2016a and it works just fine.

I just installed 2019a and it still gives the same error of too many output arguments

@Adeyemi Alabi

Did you check whether you have a psat settings.m file such as I described in my Answer below?

I suspect that you have a file named settings.m that is interfering with the operation of MATLAB.

which -all settings

You should see something like toolbox/matlab/configtools/settings.m

[ABU SADAT MOHAMMAD SAYEM]

I get below response :

>> which -all settings

C:\Program Files\MATLAB\R2020b\toolbox\psat\settings.m

C:\Program Files\MATLAB\R2020b\toolbox\matlab\configtools\settings.m % Shadowed

Then I tried to move the path file at the bottom and opened PSAT got warning messages like this :

Warning: fm_lib.mdl, line 238: Registration key for 'psatdomain' is invalid.

> In load_system (line 21)

In psat (line 827)

Warning: fm_lib.mdl, line 271: Registration key for 'psatdomain' is invalid.

If I try to save any model this error message shows "

##Even if I try to run an example in 'Simulink' error message "Too many output arguments" pops up.

How to solve this issue?

[Walter Roberson]

Which version of psat are you using? psat2.1.10 does not have any settings.m

[ABU SADAT MOHAMMAD SAYEM]

I have tried with 2.1.11 and Matlab R2020b. Should I try version 2.1.10?

[Walter Roberson]

Where are you getting your psat from?

[ABU SADAT MOHAMMAD SAYEM]

From the professor's website.

[Walter Roberson]

Can you post the link, and would I be able to access it to examine it?

Odd, I have a psat 2.10 directory that is missing a lot of what is in those... I wonder where I found it.

The settings.m that is used in psat is a problem, but one that is not too difficult to deal with. If you just rename or delete the file, then the existing psat.m will build internal settings.

The whole bit about registration key being invalid is more difficult. I am not positive, but I suspect it is because there is no psatdomain.ssc "domain" declaration file.

If it worked before in past MATLAB releases but does not work now, then maybe that has something to do with the fact that a few releases ago, Simscape was moved from being Simulink only to being usable from MATLAB as well -- that is, there were changes to Simscape a few releases ago, so it would not be out of the question for this to be one of them. However, a .ssc domain file was expected even back in (say) R2017a, so this would not seem to be a new problem.

[Adeyemi Alabi]

previously accessible file "C:\Program Files\MATLAB\R2019a\toolbox\pasat\settings.m" is now inaccessible

This is the error i get when i delete the settings.m file as you have suggested

[Walter Roberson]

After that,

rehash toolboxcache

[Amirul Hakim]

then should i install the older version of matlab?
