I need to draw some steepest descent curve emanating from saddle points of a complex (or real) function, as well as, emanating from any particular point of interest except the saddle points. I want to draw the curves with wxMaxima.

May be I should plot the negative gradient of the function, but how should I specify the emanating points? Can you please help me by sharing wxMaxima codes to plot so?

To be more specific, I want to draw the contours shown in the following link : Asymptotic evaluation of integral method of steepest descent
