MATLAB: Who i can extract which row hasn’t ‘NaN’ vector

Question

hello, i wrote this code:

damii(sac,xal)=isnan(1./R(sac,xal))
so who i can extract which row hasn't 'NaN' vector

Answer 1

See

doc isfinite  % instead

or ~isnan()

You've written an expression for an individual element of dmii unless sac and/or xal are vectors (I'm guessing not?).

To get the row of an array, use

idx=~any(isnan(dmii),2);  % column vector for no NaNs in row
res=dmii(idx,:);          % select those rows.

You can, if don't need the locations for other purposes wrap the reference directly and eliminate the temporary--

res=dmii(~any(isnan(dmii),2);
