Hello
I use the length command to see the length of some of my variables, although they include NaN's inside by a previous script I used so as to fill them and compare them Is there a way to find the length of the data non-taking into account the NaN?
I tried nanlength , as you can use nanmean etc. although it does not like it
it gives me this error
Undefined function 'nanlength' for input arguments of type 'double'.

Keep in mind that length does not give the number of elements in an array: for this you should use numel .

This works:
nonan_len = length(x(~isnan(x)));

If x is your vector.
YourLength = length(x) - sum(isnan(x))
