How to ask for the linear combination on matlab?

Hi, I'm not sure how to input this problem into matlab. this is the problem:

In P5, let S = {−3t4 + 5t3 − 2t2 + 5t + 1, −3t5 + 2t4 − 3t3 − 5, 5t5 + 3t4 − 5t3 − t2 − 4t,

−4t5 − 2t4 + 4t3 + 3t2 + 2t + 3, −4t5 − 2t4 + 3t3 − 4t2 + 7t − 7}, and let

g(t) = −3t5 − t4 + 2t3 − 2t2 + 4t + 5. Is g a linear combination of the polynomials in S?

How would you do it on pen and paper?
