inttrap

integration of experimental data by trapezoidal interpolation

Calling Sequence

v = inttrap([x,] s)

Arguments

:x vector of increasing x coordinate data. Default value is

1:size(s,’*’)

: :s vector of y coordinate data : :v value of the integral :

Description

Computes:

s(i)=f(x(i)) and x0=x(1), x1=x(n)

where f is a function described by a set of experimental values.

Between mesh points function is interpolated linearly.

Examples

t=0:0.1:%pi
inttrap(t,`sin`_(t))
