I got a question regarding the matrix of linear transformation.
If a linear transformation T: R^3 -> R^2 implies that T(1,2-1) = (1,4) ; T(-1,2,1) = (5,9) and T(2,2,1) = (2,1).
Is the most commen the method of determining the matrix of linear transformation???
M * T = n => T = M^-1 * n.
Where M is matrix the set equations in R^3, n being the vector coordinants in R^2, and T the matrix of linear transformation.
