temporal disaggregation

Dear all

I have the following data set

   dates                  price
          23/11/08               2

     28/12/08                   3

      25/01/09                   4

The first value is of 4-week average (average of prices across 28 days). The next value is a 5-week average and the last one is a 4-week average. I want to calculate average monthly prices. Temporal disaggregation is what I have in mind. Any code/suggestion?

Use interp1(), as discussed in http://www.mathworks.com/matlabcentral/answers/41250-interpolation-to-specific-sequence-of-dates
