This Challenge is to verify a Criss-Cross matrix has no invalid words,contains all of the word set, and all are simply connected (Up/Down/Left/Right). Separation, UDLR, must exist between non-intersecting words. Diagonal is considered separate.The word set is a cell array. The matrix is an array of Char with spaces being represented by '`', char(96), which is under the tilde on my keyboard.Example:Input:<pre class="language-matlab">dict={'abcd' 'cag'}
</pre><pre class="language-matlab">Achar=['abcd'
 '``a`'
 '``g`'];
</pre>Output: Validity (1 for Valid, 0 for Invalid)Related Challenges:This Challenge is derived from GAMES August 2013 Contest "On the Ice" to fit all NHL Team names into a minimum area grid using the Criss-Cross rules.
Current Best solution is 19x19, 6/3/2013. Contest ends 8/31/2013.1) Create an NHL Criss-Cross (Score by Area)2) Complete a Criss-Cross3) Create a Criss-Cross dictionary from a matrix
