Let's rewrite the right side slightly.
L(x/y/z)=(x+y+z)=(1x+1y+1z)=(111)(x/y/z)
So if L(xy/z)=(111)(xy/z), then the matrix for that linear mapping (wrt the standard basis) must be?

Why is the Jacobian matrix equal to the matrix associated to a linear transformation?
Given the linear transformation f, we can construct the matrix A as follows: on the i-th column we put the vector f(ei) where E=(e1,,en) is a basis of Rn.

I have a question regarding matrix transformations. I am trying to transform a parallelogram into the unit square. I need to find a series of matrices which transforms each point.
For example, how do I find a, b, c and d (matrix) when (0,1) is part of the unit square and (3,10) is the original point?
[a b] [3 ] = [0] [c d] [10]
