Bifurcation kit

Hello everyone,

I am a new user of Julia. I am currently using bifurcation kit to solve the simple circle equation such as : x^2 + y^2 = 1 and perform continuation and trace a complete circle with x as my variable and y as parameter.

The issue currently I am facing is the br.sol does store all the solutions I need both negative and positive values required to trace a circle. But when I use the command plot(br) to plot a circle I could just trace upper half of circle and the continuation fails at fold points. What can I do to rectify this issue I am facing?

Also is there a possibility to do the same using bordered linear solver method given in the documentation using matrix free approach.

Could you please let me know how to solve this problem. If you need any further information please let me know. Thanks in advance. @mkitti
