@HenrikSchumacher Even If I add a fictitious variable k in FindRoot with arbitrary initial value, it finds a singular Jacobian at the initial condition points. See here i63.tinypic.com/2is6omd.png . I do not why.

| Nov 10, 2018 at 17:43 | comment | added | apt45 | @HenrikSchumacher thanks for the suggestion. The point is that I have 13 equations from the system + the 2 constraints $\vec{x}.\vec{x}=1$, $\vec{y}.\vec{y}=1$ which gives 15 equations. On the contrary, I have only 14 variables. So, FindRoot complains that the numbers do not match. | |

What about FindRoot?
