I need help in simultaneous equations: My questions is, I have Matrix A (3x3) and varialble x(3x1) and b(3x1). i.e. Ax=b. we can prove it. But, how to solve to get back of Matrix A(3x3) by using matrix x(3x1) and matrix b(3x1). pls help me. thanks

Ax=b where A(3x3),x(3x1),b(3x1). here x(3x1) is unknown and can be found by cramer's rule. but by question is, After got the values of x(3x1). i need to verify or calculate the matrix A(3x3) by using x(3x1) and b(3x1).

You cannot do so. There is insufficient information do do this. No mathemagic will work.

Using structs. they can be helpful

How does use of a struct help the user solve an underdetermined linear system of equations?
