MATLAB: Estimate length with out NaN’s

Question

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'.

Answer 1

This works:

nonan_len = length(x(~isnan(x)));
