SUMMARY
The discussion centers on determining values of b in the matrix equation y = Cx, where C is a 4x4 matrix. The user seeks to identify conditions under which the system does not yield a unique solution. It is established that a unique solution exists when the rank of matrix A, denoted as r(A), equals the number of variables n. The user primarily utilizes MATLAB for calculations and is looking for methods to compute r(A).
