intsplin — integration of experimental data by spline interpolation
v = intsplin([x,] s)
| x | : vector of increasing x coordinate data. Default value is 1:size(y,'*') |
| s | : vector of y coordinate data |
| v | : value of the integral |
computes :
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))
