Why is fimplicit not plotting x^2 = 0 ??
7 ビュー (過去 30 日間)
I have a code that takes in an implicit function from the user and then plots it. However, I ran into this odd problem where fimplicit is not plotting anything when the function is x^2. The code I entered :
fimplicit(@(x,y) x.^2,[-5 5 -5 5],'b-');
The output is just a plain white plot. No blue line at x=0. However, if I simply change my function to x.^2 - 1, everything works as expected. I'm guessing there is some trouble caused by the fact that x^2 is "tangential" to zero. (I know that this may be incorrect terminology.)
Is there any workaround for this?
EDIT: I am looking for a fix not only for the case of x.^2. The recommended solution must also be able to plot implicit functions as that is the primary requirement.
