 |              This is a matlab function which return 
 |              suitable indexes for all given codes.
 |
 |              If suitalbe indexes are not foud returns -1 
 |                
 |
 | Limitations:
 |              Code lengths must be in between 2^2 ... 2^8
 |              The index must be greater tahn 0 and less or equal
 |              to code length      
 |        
 | Depends on files:
 |              code.c  and code.h     
 |     
 |  Function call: 
 |                index = c_get_code_indexes([4 4 4 4 4])
 |                retruns :
 |                       index =  2     3     4     1    -1
