inttrap
integration of experimental data by trapezoidal interpolation
Syntax
v = inttrap(s) 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))
