Extracting a matrix from linear expressions
Suppose I have a vector depending on symbolic parameters, say v=vector([a-b, b-c, c-a])
. How to extract the matrix naturally associated with the vector v ? I mean the matrix M
1 -1 0
0 1 -1
1 0 -1
since vector([a, b, c]) * M == v
. In fact I need the equivalent to the Maple command GenerateMatrix.
