integration of an expression by quadrature
y = integrate(expr, v, x0, x1) y = integrate(expr, v, x0, x1, atol) y = integrate(expr, v, x0, x1, atol, rtol)
x1(i)
.
y = integrate(expr, v, x0, x1 [,atol [,rtol]])
computes
for
i=1:size(x1,'*')
, where f(v)
is given by the expression expr
.
The evaluation hopefully satisfies following claim for accuracy:
abs(I - y) <= max(atol, rtol*abs(I))
where
I
stands for the exact value of the integral.
