need help to find out the element of a Matrix from matrix multiplication equation.
A=[a1 a2 a3 ........an] (1 by n matrix)
B=[b1 b2 b3.........bn]T (n by 1 matrix)
A.B=1 .........(1)
I know the elements of A matrix.
could any body help me to find out the element of B matrix?
P.S.: A and B are not the square matrix.

This cannot be done.
Think about this: ![A=[2~3]~\&~B=[x~y]](http://latex.codecogs.com/png.latex?A=[2~3]~\&~B=[x~y])
then ![A\cdot B^T=[2x+3y]](http://latex.codecogs.com/png.latex?A\cdot B^T=[2x+3y])
.
There are infinitely many solutions for
