Hi,
I have a 3D matrix size 951x301x720 let call it A.
I want to get a 951x301 matrix B with the mean of A over the third dimension.
I computed the mean over the third dimension with B = mean(A,3) but I have a lot of zeros in my matrix and I do not want the mean to be affected by the 0 values.
How can I ignore the 0?
Thank you

You can set 0 values to NaN. Then find the mean of non NaN values;
Ap=A;
Ap(Ap==0)=NaN;
B=mean(Ap,3,'omitnan')
