If I have the matrix A=[1 2 3;4 5 6;7 8 9] and the matrix B={1;2;3}



of course A*B is C={14;32;50}.





My question how can I get the matrix A if I have B and C ?
thank in advance

It is not possible. It can be explained, at least, in three ways:

1. It is equivalent to solve a system of three equations and nine unknowns.

2. The inverse matrix is only defined for a square matrix.

3. The matrix A that satisfies the equation is not unique: Any new matrix obtained by a linear combination of rows or columns satisfy also the equation.
