Why do I get an "End-of-ce​ntral-dire​ctory signature not found" error when I unzip the MATLAB installer?

When I unzip the MATLAB installer file in Terminal, for example:

user@host$> unzip matlab_R2011b_glnxa64_installer.zip

I receive the following error message:

 "End-of-central-directory signature not found.  Either this file is not a zip file, or it constitutes one disk of a multi-part archive.  In the latter case the central directory and zip file comment will be found on the last disk(s) of this archive."

What does this mean, and how do I proceed from here?

You will receive this error when the file is either corrupted or an incomplete download. Please retry downloading the files from the following link:

http://www.mathworks.com/downloads/web_downloads/ (MathWorks account log-in and download permissions required).

Please try using the automatic download agent or manual download. If the error still occurs, please try downloading the files from a different computer.

Alternatively, starting with MATLAB R2008b, if you are the Administrator or Asset Manager of a license, you can download an ISO image of the installation DVD's for MATLAB. In order to access the ISO image, access your MathWorks account here:

www.mathworks.com/downloads/web_downloads

The ISO image link can be found on the right after you click "download"

NOTE: MathWorks does not offer ISO images of versions prior to R2008b.
