Error message Undefined variable isnan
显示 更早的评论
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.

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),:)
