Hi everyone,
I have an array like this:
tnCT =
3.0070 NaN
18.0067 3.4871
34.0071 4.6240
48.0062 4.9370
138.0044 5.9247
153.0041 6.6163
I want to set to 0 the row that has NaN on it. I have tried the following:
for i = 1:length(tnCT)
if isnan(tnCT(i,:))
tnCT(i,:) = 0;
end
end
So I will end with:
tnCT =
0 0
18.0067 3.4871
34.0071 4.6240
48.0062 4.9370
138.0044 5.9247
153.0041 6.6163
Can you please tell me what is wrong with my approach, since it doesn't work? Removing the values also would do the trick (since in the next step I create a nonzeros matrix)

mask = any( isnan(tnCT), 2 ); %find rows with nan
tnCT(mask,:) = []; %delete them
