I need to run Ansys from Matlab. I write the code
dos('ansys145 -b -i model2.txt -o output2.txt');
Then I get an error
ansys145 is not recognized as an internal or external command, operable program or batch file.
I try adding "C:\Program Files\ANSYS Inc\v145\ansys\bin\winx64\ANSYS145.exe" as a path to Environmental Variables but the problem is not solved.

See ANSYS for the MATLAB AAS Toolbox interface.

As of today, the provided link
redirects to the Ansys start page. The latest ANSYS_aaS Toolbox I could get is 1.1.9, which officially works until Matlab R2018b. I couldn't get it to work with newer releases and also can't downgrade my Matlab release because I'm using some functionalities of newer releases. Is there any follow-up on this? Has Ansys aaS been discontinued?

Thanks for providing the new link. Still, the time stamp is from 2017 and according to the text, the toolbox works for Matlab releases from 2014b through 2016a. It would be great to get an update on the state of things (@Sarah Palfreyman, @MathWorks Support Team).

I updated it and It support all Matlab versions from 2014b to 2023b and ANSYS versions from R15 to R23.2
Thank you
