RMS Function Returns NAN
60 views (last 30 days)
I am using the 'rms' function to calculate root mean squared values. For certain portions of data, the function returns NAN. There is good, non-zero data in the array i'm inputting (2000 data points all non-zero). I know how to calculate rms values myself, but for the sake of learning, i would like to know why this is happening.

It's likely you have NaN in your input, or your input is an empty vector.
If you wish to exclude NaN values from computation, then you can try:
sqrt(mean(x .* x, 'omitnan'))
Hope this helps,
