m？ =? [ 100,200, 1000];

For what? i= 1:3

The% interval is divided into n equal eldest son intervals.

n？ =? M (1);

xn？ =? (0:n- 1)/n * pi； ? %xn(i) is the value of the left end point of the I-segment interval.

d？ =? pi/n； ? % subinterval width

xnm？ =? xn+d/2； ? The midpoint of the% interval

ynm？ =? f(xnm)； ? Function value of midpoint in% interval

S(i)？ =? Sum (ynm); ? % sum

end

Average percentage

Smirne? =? Sum (S)/ sum (m)? % function average
