Create an ellipse with equal distance between two points

I have created an ellipse as shown
The distance between two consecutive nodes is different I want to create an ellipse with constant distance between the nodes (e.g. 0.125)
Is there any way that I can do this?
Thanks in advance
ellipCenter_x = 0;
ellipCenter_y = 0;
ellipRadius_x = 8;
ellipRadius_y = 2.5;
theta = 0:0.1:2*pi;
x1 = ellipRadius_x*cos(theta)+ellipCenter_x;
y1 = ellipRadius_y*sin(theta)+ellipCenter_y;
x1(end) = x1(1); y1(end) = y1(1);
plot(x1,y1,'ro','Linewidth',0.5);
axis equal

How you are measuring the distance from one node to other?
Coordinates of each point is stored in ' x1 ' and ' y1 '

The simplest way to do this is to use my interparc tool.
Just take the set of points on the ellipse. Then pass them into interparc.
pt = interparc(100,x1,y1,'csape');
plot(pt(:,1),pt(:,2),'o')
axis equal
interparc is on the file exchange, here:
Could you solve this using other tools? Well, yes. I can think of several ways to do so. But they would all take at least some thought, and are not worth the effort when a trivial solution is already available.

I get an error... when attempting the above:
CSAPE was requested, but you lack the necessary toolbox.
oh no. is this something Matlab has discontinued? and if so, I hate when that happens
ok Replace
'csape' with 'spline'
and it will work!
