Hi . my problem is that for programate the line 0 in octave can be this form: >y(1000) =0; the line y=0 be in all range [0:1000], but I like that the line can be in the range 1901:2005 for example, for add to time series up -down the line 0!!,
How is the form of programate this sequence?. Thanks People. Alvaro Gonzalez. R
