Do you know which index that the year 2006 corresponds to in the second matrix? (Where does the data stop for 2006?) Similarly, does your matrix tell you which year corresponds to which data point?

Based on what you told me, let's say that the data for the years 1984-2009 is stored in matrix A, you would simply do:
B=A(1:276,1);
Where B is the matrix containing the data from 1984 to 2006 if the year 2006 ends at the 276th row.

By the way, you're not changing the dimension of your matrix. What's you're doing is extracting a portion of A into a new matrix B. Nothing got changed.

Try interp2() or (much, much easier) try imresize() if you have the Image Processing Toolbox.
