Hello,
I got a matrix and one value is missing. I still wan to calculate the standard error of it
>> test=rand(3,3)
test =
0.0975 0.9575 0.9706
0.2785 0.9649 0.9572
0.5469 0.1576 0.4854
>> test(3,1)=missing
test =
0.0975 0.9575 0.9706
0.2785 0.9649 0.9572
NaN 0.1576 0.4854
>> test_SE=std(test)/sqrt(length(test))
test_SE =
NaN 0.2679 0.1595
Why doesn't it work?
And can I let Matlab ignore the missing value?
Thanks.

doc nanstd
Or fill NaN values using fillmissing and use std.
Or have a look here:
