integration of experimental data by spline interpolation
v = intsplin([x,] s)
: :s vector of y coordinate data. : :v value of the integral. :
Сomputes :
Where f is a function described by a set of experimental value:
s(i)=f(x(i)) and x0=x(1), x1=x(n).
Between mesh points function is interpolated using spline’s.
t=0:0.1:%pi
intsplin(t,`sin`_(t))
