intsplin

integration of experimental data by spline interpolation

Calling Sequence

v = intsplin([x,] s)

Arguments

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

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.

Examples

t=0:0.1:%pi
intsplin(t,sin(t))
