Missing NaN functions?
显示 更早的评论
When I type >>help nansum in the command window, matlab returns "nansum not found." even though the function does exist in the documentation for the R2011a version. Is it possible that these functions (i.e. nansum, nanmean etc.) didn't install correctly, were they not included in R2011a, or do they exist under a new name? Thanks!

nansum is part of the optional Stats toolbox, and also the optional Finance toolbox, but not part of basic MATLAB.
There is a MATLAB File Exchange contribution that implements at least some of these; please see the contribution http://www.mathworks.com/matlabcentral/fileexchange/6837-nan-suite/

so nansum
Xnan20 = X;
Xnan20(isnan(X))=0;
out = sum(Xnan20);
