Name
inttrap — integration of experimental data by trapezoidal
interpolation
Calling Sequence
v = inttrap([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 linearly.
Examples
t=0:0.1:%pi
inttrap(t,sin(t))
