I have the system of equations Ax=b.How can I solve it for A if I know the  x and b matrices??
And can I use the lscov() function too??

Hi Betty,

How many rows and columns in the x and b matrices?

Thanks.

Rick

One solution is

A0 =3D b/x

It is unique if and only if there is
no A for which

A*x =3D 0.

Hope this helps.
