I need to convert my time vector t = 723 x 1 in the format of 10-day cycles into just days, still keeping the same 723 size.
the time data looks as follows:
1993.0145264
1993.041626
1993.0688477
1993.0959473
1993.1231689
1993.1502686
1993.1774902
1993.2045898
1993.2318115
1993.2590332
1993.2861328
1993.3133545
1993.3404541
etc. etc...
I need this for calculating harmonics...
thanks, Michael

Presuming from the format it is year.fractionaldays
>> diff(t)
ans =
0.0271
0.0272
0.0271
0.0272
0.0271
0.0272
0.0271
0.0272
0.0272
0.0271
0.0272
0.0271
which shows is a constant dt. Thus, you can simply again use linspace with an arbitrary starting value and whatever units for delta-t desired over the length of the series. The actual values are immaterial.
