Returning last value of while loop
显示 更早的评论
I need to return the last integral of the while loop, the one that is small enough to satisfy the inequality, so that the function value (q) is equal to H with the last value of k. How can I do that?
function q = myimproperintegral(f,a,b,tol)
syms x;
k = 2;
H=0;
before = int(f(x),(a+(b-a)/k),b);
after = int(f(x),(a + (b-a)/(k+1)),b);
while before-after > tol
k=k+1;
H=int(f(x),(a+(b-a)/(k+1)),b);
end
q=double(H)
end

You can return multiple outputs with functions
function [q, k] = myimproperintegral(f,a,b,tol)
