You must have a variable defined as either mean, var, or std. Clear your workspace and try again.

areas = [5176 5183 5165];
area_mean= mean(areas)
area_mean = 5.1747e+03
area_var= var(areas)
area_var = 82.3333
area_std= std(areas)
area_std = 9.0738
% Now to recreate the error by replacing the function 'mean' with a variable
mean = 5
mean = 5
area_mean= mean(areas)
Index exceeds the number of array elements (1).

'mean' appears to be both a function and a variable. If this is unintentional, use 'clear mean' to remove the variable 'mean' from the workspace.
