Re: How to extract sequenced data from an array?

[Francesco Potortì]

Maybe you are looking for something like this?

octave> a=[1 7 3 8 5 6 1 0 8 7 6 3 9 7 1 7 3 8 5 8 3 2 1 5 6 9 8 7 4 0 2 3];
           *********___________________*********__________________________


octave> c=conv(detrend(a),detrend([1 7 3 8 5]))
c =

 Columns 1 through 7:
    8.06818  -16.47012   17.40918  -25.08065   23.90000  -15.20000   21.20000
 Columns 8 through 14:
   -9.00000  -12.00000    3.50000   -6.30000   18.40000  -16.20000   11.10000
 Columns 15 through 21:
    0.80000   -7.60000   15.60000  -28.20000   23.90000  -19.20000   23.40000
 Columns 22 through 28:
  -10.40000    9.20000  -16.40000    1.50000   -9.30000   11.00000    0.40000
 Columns 29 through 35:
   10.40000    3.80000   -7.90000   -1.80000   -9.72419    4.19593    0.55621
 Column 36:
    2.44545

octave> find(c>max(c)*(1-sqrt(eps)))
ans =
