Mean doesn't work

Hi, I have doubt in mean. if we have more than 10000 rows why mean doesn't work actually sum also does not work. for example, All_measured = 43472*30 double and the mean formula: mean(All_measured ,2) but the answer is 43472*1 full of NaN Any suitable ideas are very appreciable.

Try this:

mean(All_measured ,2, 'omitnan')

or:

nanmean(All_measured ,2)

Hi,

Thanks a lot for the function. And if I will use same format for standard deviation (S = std(All_measured,0,2,'omitnan')), it would be correct?

Best, Venkat

My pleasure.

Yes.

I would change your assignment slightly, to:

S = std(All_measured,[],2,'omitnan')

The ‘[]’ indicates that an argument (here,the weight vector) is not supplied, instructing the function to use its default values, rather than giving it a numeric value.

Perfect. Thanks a lot.

As always, my pleasure.
