findcells

FINDCELLS performs a search on MATLAB cell arrays of structures
   
 INDEX = FINDCELLS(CELLARRAY, 'field') 
   returns indexes of elements that have a field named 'field'   

 INDEX = FINDCELLS(CELLARRAY, 'field', VALUE) 
   returns indexes of elements whose field 'field'
   is equal to VALUE1, VALUE2, ... or VALUEN. Where VALUE can either be
   character strings or a number. If its a character string REGULAR
   expressions can be used.

 Example:
   findcells(THERING,'Length',0, 0.2);  % will match elements of
                                          lengths 0 and 0.2
   findcells(THERING,'FamName','SFA','SDA');
