MATLAB: How to find mean with nan

Question

Hi!

I want to find mean with nan values and with different step. My script is:

RowDivision=[1,46,172,305,472,618,714,784,920];

nElement=diff(RowDivision); % step

meanG=cellfun(@mean,(mat2cell(G,nElement,ones(size(G,2),1)))); %mean

but if i have one only nan value i.e. from 1 to 46 the mean is nan. How can I ignore the nan? Thank you!

Answer 1

a=[1 2 nan 3  nan 10]
nanmean(a)

%or

mean(a(~isnan(a)))
