I know Yellowstone is basically a volcano that is overdue to blow up, but is it still giving off lots of CO2 and SO2 from the pools and paintpots that can pollute the air?

say you have C=(0 1 0 0), and A =
0 0 1 0
0 0 0 1
-1 1 0 0
1 -2 0 0

how do you get an outcome?

do you do c_1 * a_11 + c_2 * a_12 + c_3 * a_13 + c_4 * a_14, etc.? or something else? (underscore meant to denote subscripts).
