Hi Enrique,

Could you please tell us which version of matlab you are using? Also please try to restart matlab, and then open the same model and then Requirements Manager. Check if you can open the Requirements Manager. If not, please check the error message. We want to know if the same error message is shown.

Thanks,

Yongjian

One more question. Are you using Subsystem Reference in your model by any chance?

[Enrique]

The version of matlab is shown in the right column, which is R2019b. Yes I have tried to restart and open the model the following message is shown (I believe they are the same):

Warning: Error occurred while executing the listener callback for event ReqPerspectiveChange defined

for class slreq.app.PerspectiveManager:

Dot indexing is not supported for variables of this type.

2019b is old. Any reason not using newer versions?

Hello Enrique,

I understand that you are encountering errors while trying to open the ‘Requirements Manager’ app from the ‘Apps’ tab in MATLAB.

In this case, as a workaround, you can try opening the Requirements Editor using the following command in MATLAB R2019b:

slreq.editor

For more information on opening Requirements Editor, you can refer the following link: https://in.mathworks.com/help/releases/R2019b/slrequirements/ref/slreq.editor.html

Further, you can also try upgrading to MATLAB R2022a or a later version and use anyone of the following options:

1) Use the ‘slreq.openRequirementsManager’ command. An example for this is given below:

open_system('model_name');
slreq.openRequirementsManager('model_name');

For more information, refer this link:

https://in.mathworks.com/help/slrequirements/ref/slreq.openrequirementsmanager.html

2) Open the Requirements Editor app using any of the following ways:

a) Simulink Toolstrip: On the ‘Apps’ tab, under ‘Model Verification, Validation, and Test’, click ‘Requirements Editor’.

b) MATLAB Toolstrip: On the ‘Apps’ tab, under ‘Verification, Validation, and Test’, click ‘Requirements Editor’.

c) Type this command on MATLAB command prompt,

   slreq.editor

For more information on the same, refer the link below:

I hope this helps.
