Algorithm of Minimum Arc Approximating Curve and Realization in Matlab

Introduces the algorithm of three points arc in maximum error approximating curve,theoretically making arc approximated sections minimum.Based on Matlab nodes are solved through programming,and theoretical arc is replaced by arc of equal chord and equal arc length to search for initial value of node so as to ensure reliable and rapid running of the program.Arcs have smooth connections and numerical control program segments are less and efficient.
