Parametric Function does not show up in plot?
显示 更早的评论
I am attempting to plot the Folium of Descartes in Matlab as a set of parametric equations, but when I use the plot(x,y) command no plot shows up--just an empty plot with no lines or points.
These are my commands I am using--hopefully someone can point out any mistakes I may have made.
clc
syms t
t=linspace(-30, 40);
x=3*t/(1+t.^3);
y=3*(t.^2)/(1+t.^3);
plot(x,y)

You don’t need syms but you do need to vectorise the division (replace (/) with (./)):
t=linspace(-30, 40);
x=3*t./(1+t.^3);
y=3*(t.^2)./(1+t.^3);
plot(x,y)
