NaN data treatment: can I get a mean f a vector including NaN?

Hello,

The title says it all. Can I get a mean of a vector including NaN? For instance, a= [1 2 3 NaN 4 5] mean(a) usually gives NaN. But I wonder if there is any command or way to get a mean of 3 there. 1. NaN is treated to be missing so that is counted as zero and 2. 1+2+3+4+5 is divided by 5 not by six, which counts NaN.

Thanks

nanmean() if you have the stats toolbox. If you do not there is a File Exchange Contribution with a title similar to "nantools"
