I think we need to improve our error messages here. For us, a valid start solution is a non-singular start solution (i.e. the Jacobian needs to have full column-rank) . However, for your system the Jacobian of [f1,f2] at (0,0) is [0 0; 0 0] and therefore the solution is considered invalid.
Thanks for the clarification, was able to debug and fix my code based on that.
I am attempting to use the
monodromy_solve
function on a complex system of polynomials of high degree, but I am obtaining the warning messageWarning: None of the provided solutions is a valid start solution.
frommonodromy.jl:788
.I attempted to implement a very simple system to better understand how to use the
monodromy_solve
function, however I seem to be having getting the same error.Clearly, the starting point [0,0] is a solution given
f1(0, 0) == 0
andf2(0, 0) == 0
. As such, I do not understand why it is reporting that the starting point is invalid and I feel that I must be misusing the API/monodromy in a way that is not obvious to me.Additionally, I have a version of the code working for the 1D case, but only get this error message when dealing with a multivariate system.
