# Math Help - MATLAB Problem

1. ## MATLAB Problem

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.

Im not going to check that the units are right, so you will have to do that yourself:

Code:
T=[100:10:1000]';
P=[100:10:1000];
R=0.2870;
PP=1./P;

v=R.*(T*PP);
with each row containing the values for each pressure corresponding to a given temprature.

.

[/code]

This is similar to what I was trying. Thank you
