I'm currently using imagesc and imcontrast.
I was curious if it possible to have a script where it will automatically scale display range to eliminate outliers: 2% instead of manually changing the contrast when the figure is up.

Ran in:
y = randn(50, 50);
y (20, 20) = 1e8; % outlier
subplot(121)
imagesc(y); % outlier removed
colorbar
subplot(122)
imagesc_autoscale(y); % outlier removed
colorbar
function imagesc_autoscale(x)
s = prctile(x, [2 98], 'all');
imagesc(x);
clim(s);
end
