Hi I have a rectangle with rounded corners which I got through this:
figure
rectangle('position',[0 -1 10 2],'Curvature',[1])
axis equal
grid minor
But I need to get a list of x,y coordinates starting at the middle of the bottom line. it would also be useful to vary the number of coordinates I can get.
I'm trying to get draw a plate (basically a rectangle with rounded corners). If I don't use the function I did before how could I do it? essentially the x-coordinates would be the length of the plate, and the y-coordinates would be the height. I'm trying to get a number of x,y coordinates (which I can vary, say 200 coordinates to start with) starting at the middle bottom of the plate and then going anti-clockwise around the plate.
So to recap, starting at the middle bottom of the plate i need to get around 200 x,y coordinates anti-clockwise back to the middle bottom of the plate, but these coordinates have to follow a specific geometry (for now the shape of the plate, I think later I might change the shape.
[So i need a continuous path of points, equal distance from each other, following the perimeter of a shape/drawing/line/etc.]
I'm finding it really hard to explain, I hope this helps at least a little.
Regards,

Yeah, it can be confusing for newbies. I find it helpful to followi the examples that are included in all matlab functions in the documentation. For example, here's the example section for interp1
