Hello - I'd like to know how to get the final interval spacing used when the quad functions converge (quad, quadl or quadgk). Is there an undocumented output variable that might help me here?
Thanks!

f = @(x)sin(x);
fpeek = @(x)peek(f(x),x);
quad(fpeek,0,pi);
[fq,xq] = peek()
Here xq is a cell array where xq{i} has the points evaluated by quad at step i and fq{i} has the corresponding function values. To get just the list of points evaluated, run
xall = sort(cell2mat(xq'))
