Abstract
The method of Hiroshi Akima gives a curve which ensures - smoothness of first derivatives at the data points. The method consists of fitting cubic polynomials between every Pair of Doints (x1,y1.), 1 = l(l)n. The slope of the tangent tk to the curve at a specific point (xk' Yk) is obtained lecally by using the; coordinates of the five points (xk-2' Yk-2)' (Xk-l' Yk-l)'13; quot; (Xk' Yk)' (xk+l' Yk+l) and (Xk+2' Yk+2) of which (xk'Yk)13; is the middle member, Let the slopes of secant joining13; quot; (Xk' Yk) and (xk+l' Yk+l) be mk.
