I need a little help please..

Using the ideal gas law solved for v. v= RT/P

Find the specific volume for air, for temperatures from 100 to 1000 K and for pressures from 100 kPa to 1000 kPa. The value of R for air is 0.2870 kJ/(kg K). Your answer should be a 2 dimensional matrix.

How would I go about applying the formula and the values of pressure and temperatures and air and make that a 2 dimensional matrix? Any help would be appreciated.
