Autostart with Powershell via USB?

I have programmed a matrix the code is here:

function generateRnd {

$ buffer = [console] :: BufferWidth

[string] $ rnd = random -Minimum 1000000000 -Maximum 9999999999

while ($ rnd.Length -lt $ buffer) {

$ rnd = $ rnd + $ (random -Minimum 1000000000 -Maximum 9999999999)

}

return $ rnd.Substring (0, $ buffer)

}

[console] :: ForegroundColor = "Green"

[console] :: BackgroundColor = "Black"

while (1 -eq 1) {

echo $ (generateRnd)

Sleep -Milliseconds 1

}

Now I want to reintun that in a USB that should start automatically on my laptop, how should I proceed?

Or, how can I let it run automatically?
