I would like to know how to get the separatrices in the 2D matrix (stream function value). If anyone can suggest me on it will be of great support.

Thanking you

Yeah, finally I have to program over a matrix. But I would like to know how to start for a given 2D matrix

Thank you for the materials. I hope I ll get the direction to the solution from the materials

I have noticed that the solver requires an equation to compute and plot the phase plane line. However, I have a 2D matrix with two variables. On top of streamlines, I would like to demarcate the phase portrait line (separatrix line).
I have seen in the material it requires an equation to solve by ODE in Matlab. How should I proceed with 2D matrix case (say on top of streamlines)
