1x3−2x−5dx,
(from 0 to 1)
write a function myfun that computes theintegrand:
function y = myfun(x) y = 1./(x.^3-2*x-5);
Then pass @myfun, a function handle to myfun,to
quad, along with the limits of integration, 0 to 2:
Q = quad(@myfun,0,2) Q = -0.4605
Alternatively, you can pass the integrand to quad asan anonymous function handle
F:
F = @(x)1./(x.^3-2*x-5); Q = quad(F,0,2);
