I truly appreciate if someone answer me. I need to measure RMS of a seismic signal and I done it with the simple rms code, but my professor asked me to measure RMS of mean absolute amplitude sum(abs(a))/N). Thank you!
signal = ...;
y = rms(signal);

Try sqrt(mean(a.^2)), it should work in a simpler way.

Hi!
Have you tried:
y=mean(abs(A));
?

Exactly. Thank you!
it seems, this code "sqrt(mean(a.^2))" gives a reasonable answer.
