High School System equations - unique / no / infinite solution
Put the coefficients into a 2x2 matrix. If the determinant is 0 then the matrix is singular. A singular matrix can either have 0 solutions or infinitely many solutions.- ZannX

Graduate Solving Linear Equations with Poorly Conditioned Matrices
Yes, since fsolve is a numeric solver it would require an initial guess. I'm not sure in your case if that's feasible or not. As far as what algorithm fsolve uses, here is the link to the MATLAB fsolve function and it will give you more details...- ZannX

Graduate Solving Linear Equations with Poorly Conditioned Matrices
I'm from that thread you linked. My method of solving a poorly conditioned system is to use a nonlinear solver. If you have a system Ax = b then you can program a function in MATLAB to take an input of x and the output would be Ax - b. I.E. F(x) = Ax - b (which ideally equals 0 for the...- ZannX
