Hello everybody... I want to set an equal and fixed distance(5 units) between red star points in the whole figure(the three circles) in my attached code... How can I do it?? Please help me.Thanks in advance:)

You can set up points at equal angles using code in the FAQ. http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F However if you want the angles to be such that the arc length between the points is exactly 5 then the first and last point, near 0 and 2*pi, may not have an arc length of 5 between them unless the circumference is a multiple of 5. So it won't work for any arbitrary radius. If a spacing of 5 for nearly all pairs of points except for one pair is good enough for you, then see the 5th code chunk in the FAQ.

The formula for a hexagon is not so simple as s=r*theta like it is for a circle. Sorry but I won't have time to help you with the trig formulas and if statements to do that.

interparc() can interpolate along hexagons, provided it is given the vertices.

You cannot get equal distance of 5 units on the circumference of a circle unless the units are fractions of 2*pi. However if the units are fractions of 2*pi then you cannot get equal distances on the straight line that also has red markers.
