What version of MATLAB are you using?

Answer 1

If you need to start an independent process that stays alive while MATLAB continues then use .NET or Java

Answer 2

you can use:

!cmd &

it works for me to open the command window from Matlab

Moreover, if you want to excute something in the cmd, you can do it as follows (in my case I want to run an excutable called "Opensees" then type the file name)

!Opensees fileName.tcl &

All the above commands will open and run the excutable in an external commond prompt window. If you wish to run it inside Matalb command window, just remove the "&" symbol at the end.

I hope this helps.

P.S. I am using MATLAB R2018a - academic version

My reading of the question was that the user wanted to be able to start a command shell and have it remain open waiting for commands to be sent to it from MATLAB. The way to do that from Windows is to use .NET assemblies as I linked to before.
