Plotting powered matrices vs ezplot
显示 更早的评论
I've just come across a weird bug (or it's propably just me doing something wrong). I am doing:
ezplot(-x1/(2*(x1^2)^(5/2)),[-5,5])
which produces a fine plot. Then I am trying to do same plot by doing
x=[-5:0.01:5]
y=-x./(2*(x.^2).^(5/2))
plot(y,x)
and the plot is orders of magnitude scaled up, meaning y doesn't go from -0.5 to 0.5 like it should, but from 5*10^7 to -5*10^7. What am I missing here?

The function is discontinuous at x==0, and goes to ± infinity. You are dividing by zero.
