The reasoning is simple. MATLAB defaults to a 'jetblue' colormap when you use imshow(im). 

Typically you need to specify the colormap being used when you use imshow.

For this, add another command like:

$$colormap(gray(256));$$

to your current script.

We have a site with:


Decent ranking on certain targeted keywords.
An HTTPS-only policy, which uses 302 redirects to force clients onto the secure version of any URL.
Internal links using HTTPS, so there is no redirection.
Some, but not all, external links from other domains use HTTPS. The rest do not and will of course be subject to the 302.
Google is only indexing the HTTPS version of each URL. Even if you search specifically for the HTTP URL, only the HTTPS URL is shown in the results.


Will there be any significant, immediate ranking benefit to changing our site to use 301 redirects to enforce HTTPS? Are there any statements from Google, Matt Cutts or other authorities on this specific situation?

Based on my research the difference should be minimal since we are already well indexed, and our internal links are fine, so Google is not going to apply a sitewide penalty for the 302s, which are, in effect, only the first link in the chain.
