How could I create a mean funtion that ignores NaN values?

I am trying to find the average of a column even with “NaN” values and nanmean requies extra downloads.

Let A be your array which have NaN's.

% Remove the nan's first 
A(isnan(A)) = [] ;
themean = mean(A) ; 

Also read about mean function, it has an option to omitnans.

The mean() 'omitnan' option is what I would recommend these days, provided that your MATLAB is new enough to have it.
