How do you plot RMS of a Colormap?

Looking to get an RMS value of a 3D plot based on Z Values. I have a colormap that has speed and RPM on x and y with Z as the dependent value.

Depending on the desired result, either use the rms function with the entire matrix (using the (:) convention to force it to be a vector) or take the rms values across a specific dimension.

Z = randn(10);
rms_all = rms(Z(:))

rms_all = 1.0607

rms_across_rows = rms(Z,2)

rms_across_rows = 10×1

0.9526 0.9594 0.8025 1.1049 1.1172 1.1101 1.0367 1.2585 0.8551 1.2994
