ISLANDS finds all "islands" which are 4-connected components in a matrix. The function will return three output arguments, including the largest connected island in the input matrix. See the detailed help for all descriptions.

Inspired by a recent puzzler posted here:
and by the submission from Tim Davis.

Also included is a MEX-File version which runs faster than the M-File version.

Tested on 2007a and 2007b.

Please email me about bugs and other concerns. Thanks.
