Question

If I have a 3x3 matrix and a 3x1 vector what does determining the linear combination of the 3x1 to the vectors formed from the columns of the matrix mean?

Answer 1

if im reading it right:

Ax = b

such that you are given A and b, then x is vector that defines b as a linear combination of the vectors in A

Answer 2

\[b = x_1a_1+x_2a_2+x_3a_3\]

Answer 3

gotcha thanks.
