Error= num2str(err)
if Error(1) > 0.10000
L = 'Fail.';
set(handles.text15,'string',L);
else
L = 'Pass';
set(handles.text15,'string',L);
end
This is my program -
First In command window i am getting this answer in two lines and i want to use second, but every time it will not give two answers, but whatever the number is, i want to use last,
Error =
0.091683 0.085897
But in GUI it always shows Fail.. Why..?

You are converting "err" to a string, and then comparing the string to the numeric value 0.10000. Why are you not comparing err instead of Error?

That doesn't make sense. What Walter asked is why you don't simply do this:
if err(2) > 0.10000
L = 'Failed';
else
L = 'Passed';
end
set(handles.text15,'string',L);

If i tale only
err > 0.10000
then it takes first value of err and then works correctly, but
Currently i know in answer of err that there are two values so i can take
err(2) > 0.10000
But each time i will not know. Some time there will be 3 values or some time there will be 4.. So, i want to do such that whatever the number of values, i have only to take last..
So, i may have to apply any counting mechanism or any thing else and how..?
