I am running into a problem trying to plot a complex valued function using parametric plots.
I have a function: z = (1+I*t)^2/(I+t) Which I try to plot: parametric_plot((z.real(),z.imag()),(t,0.1,0.9)) ...and I get an error: TypeError: float() argument must be a string or a number The strange thing is that parametric_plot works fine when z is a fractional linear transformation or a polynomial. I am getting this error on both 4.0.2 and 4.3.1 Any insight into why this is happening would be greatly appreciated. -Brian -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
