You can use subs on a matrix to substitute variables by values:
sage: sample = {}
sage: sample['M1'] = matrix(QQ, 2, [7, 5, 2, 4])
sage: R.<t> = QQ[]
sage: sample['M2'] = matrix(R, 2, [t^2, 2, 3, 1 - t])
sage: sample['M2'].subs({t: 10})
[100 2]
[ 3 -9]
sage: sample['M2'].subs({t: 20})
[400 2]
[ 3 -19]
