Create logarithmically spaced vector with points spaced more closely at far end of vector

41 visualizzazioni (ultimi 30 giorni)
Is it possible to use logspace (or some other approach) to create a logrithmically spaced vector where the points are more closely spaced at the far end of the vector? For example, for the vector x = logspace(1, 2, 100), I would like to have the points spaced more closely toward the 10^2 = 100 end of the vector. I can't be the first person to want to do this...Thanks in advance for anyone's help!

Like this?
% Normal log-spaced vector
x1 = logspace(1, 2, 10);
% Create inverse log space
delta = diff(x1);
delta = fliplr(delta);
% Inversely log-spaced vector
x2 = [10, 10+cumsum(delta)];
% Check!
figure
plot(x1, 'o')
hold on
plot(x2, 'v')
legend({'x1', 'x2'}, 'Location', 'best')

Thank you for your comment. Unfortunately, it's not clear for me what the expected result looks like. Could you give us a small example?
