For-if loop not working?

A=[2 5 4 13 4 23 8 3 9 5 0];
for k=1;length(A)
    [Maxima,MaxIdx]=findpeaks(A)
    if Maxima>10
        Maxima=Maxima(k)
    end
end
Maxima

It should display...

Maxima= 13 23

However, it is displaying...

Maxima= 5 13 23 9

What am I doing wrong?

[Kevin Phung]

what are you trying to do with your forloop?

findpeaks(A) alone should just return 5 13 23 9, as expected.

https://www.mathworks.com/help/signal/ref/findpeaks.html

A local peak is a data sample that is either larger than its two neighboring samples or is equal to Inf. Non-Inf signal endpoints are excluded. If a peak is flat, the function returns only the point with the lowest index.

Lose the loop!

Try this:

A=[2 5 4 13 4 23 8 3 9 5 0];

[Maxima,MaxIdx]=findpeaks(A)
Maximav = Maxima(Maxima > 10);

Maximav

produces:

Maximav =
    13    23
