LISSAGE(1)

NAME
smooth - smoothing by spline functions

CALLING SEQUENCE
[pt]=smooth(ptd [,step])

PARAMETERS

ptd : (2xn) real vector

step
    : real (discretization step of abscissae) (default=0.01*magnitude(v))

pt  : (2xn) real vector

DESCRIPTION
this function computes interpolation by spline functions for a given set of points in the plane. The coordinates are (ptd(1,i),ptd(2,i)). The components ptd(1,:) must be in ascending order. The default value for the step is abs(maxi(ptd(1,:))-mini(ptd(1,:)))/100

EXAMPLE
x=[1 10 20 30 40];
y=[1 30 -10 20 40];
plot2d(x',y',[3],"011"," ",[-10,-40,50,50]);
yi=smooth([x;y],0.1);
plot2d(yi(1,:)',yi(2,:)',[-1],"000");
