intsplin - integration of experimental data by spline interpolation
Calling Sequence
- v = intsplin([x,] s)
Parameters
-
x: vector of increasing x coordinate data. Default value is 1:size(y,'*')
-
s: vector of y coordinate data
-
v: value of the integral
Description
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.
Examples
t=0:0.1:%pi
intsplin(t,sin(t))
