How do I execute Powershell scripts in MATLAB?

I can run Powershell scripts from MATLAB with the following syntax:

!powershell 2*10; echo 'This is a line'

However I need to press the Enter key to return to the MATLAB Command Prompt. This makes it impossible to use Powershell script from a MATLAB function or script as it needs user interaction to continue the execution of the function or script. I would like to let the Powershell command return by itself.

The Powershell application calls ReadLine() on a redirected STDIN after executing a script. Since MATLAB redirects STDIN, you need to press Enter to continue.

There is a workaround to let the Powershell application return immediately. You can pass the following input argument:

-inputformat none

For example:

!powershell -inputformat none 2*10; echo 'This is a line'
