Error message Undefined variable isnan

Hi,

I am new to using mathlab so apologies if this is obvious.

for i=1:2705

borntime(i)=min(find(~isnan(final_n(i),:)))

end

I am getting an error message saying undefined variable isnan.

If anyone could help me it would be great.

Final_n is a matrix of 2705x1209.

Thanks.

[Azzi Abdelmalek]

final_n=rand(2705,5);
for i=1:2705
borntime(i)=min(find(~isnan(final_n(i,:))));
end

the error was in

   ~isnan(final_n(i),:)

Thanks a million for that. What exactly does the

final_n=rand(2705,5);

line do?

[Azzi Abdelmalek]

it's just an example to test your code
