Spiral with constant velocity (same distance betwee coordinate)
Posted: Feb 25, 2013 10:39 AM

Hi
I have a problem creating a spiral with constant velocity (same distance between coordinates ? not constant angular velocity).

These lines of code should create a spiral with constant angular velocity:
Num = 1000; Rad = 20*pi; Width = 10;
t = linspace(0,1,Num);

These lines creates a spiral with ?almost? constant velocity:
Num = 1000; Rad = 20*pi; Width = 10;
t = linspace(0,1,Num).^0.5;

However, I want to create a spiral with constant velocity (constant distance between the coordinates) and I want to be able to change the amplitudes (i.e. y>0 coordinates should be multiplied by 1.6) without changing the velocity. Any Ideas on how to do this?

Kind regards
Markus
