Question: Use interpolation to find missing data in my table

I have a table of data that displays salaries for different jobs and how they have changed over the years. I figure that interpolation would be the best way to fill in the blanks, but im not sure of the correct syntax to accomplish this in maple, I tried using splines but i just couldnt find a suitable example in the help documentation. YEAR| 1975| 1980| 1985| 1990| 1995 ---------------------------------- job1| 7843|11314| ??? |17820|21431 ---------------------------------- job2| 8388|12409| ??? |20694|28362 ---------------------------------- job3|12332|18075| ??? |31112|36980 ---------------------------------- job4|16725|23308| ??? |41458|56667
