I face a problem with root finding. I'm solving a system of equations using FindRoot function. I received the following message "Singular Jacobian".. Is there a way to avoid this? I tried perturbing the initials and it didn't work.
I checked FindMinimum and it is used to get Minimm of function, how it is used to solve system?
Linear Equations can be easily solved by FindMinimum
equations are linear system in unknowns u[i,j]
You could try a FiniteDifference Jacobian or specify the Jacobian yourself, as described in the Options section of the FindRoot documentation.
