You just did — almost.
x = 0.5;
dB = 20*log10(x);
produces:
dB =
-6.0206e+000

My pleasure!
You should have gotten the same result in your script as with the Command Window if you entered the same commands, unless you somehow implicitly converted a1 to double before you issued your Command Window call to log10. That’s the only way I can explain it.
No questions are stupid questions. No worries.
