Hi! I am working with a 3D matrix of 360x200x60 of temperatures in dimensions of latitude x longitude x time. I want to find a way to take averaged temperature data for each of the 60 time steps, so I believe I need a list of 60 mean temperatures so that I can plot this over time. I can find means for each individual time step using the code:
nanmean(nanmean(MATRIXNAME(1:360,2:200,1)))
and changing the 1 to 2, 3, etc for each time step. Can I tell MatLab to automate this into a single list for all 60 time steps? Thank you!

M = rand(360,220,60);
timeStepMean = nanmean(nanmean(M(:,2:end,:),1),2);
You might then want to use the reshape command to make the resulting 1x1x60 vector into either a row or column vector.
