I have a Powershell script that works when called from the command line (Windows 7) but not when called using the system command within Matlab. The script searches the registry for version information from a specific vendor's software install. When I call it from the command line it generates a file containing the correct version information. When I run it using the system command in Matlab it does generate the file, but it has zero bytes (verified by opening with a hex editor).
What might be causing this?
Here is the script:
Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\ -rec -ea SilentlyContinue | ForEach-Object {
$CurrentKey = (Get-ItemProperty -Path $_.PSPath)
if ($CurrentKey -match 'Vendor') {
if ($_.PSChildName -match 'InstallProperties') {
$CurrentKey.DisplayVersion
}
}
} | out-File Vendor.txt -Encoding ascii
Here is how I call it from the command line:
Here is how I call it from Matlab:
[s,r] = system('powershell -ExecutionPolicy RemoteSigned -inputformat none -file VersionFile.ps1')
Note: the return values are s = 0 and r = ''.
I have tried removing the pipe to out-File. On the command line, I get the version number displayed in the command window. When calling from Matlab, I get the same return values shown above.
I am using Matlab R2013b.
Thank you
