Monograph title: APWCS 2010 - 2010 Asia-Pacific Conference on Wearable Computing Systems Issue date: 2010 Publication year: 2010 Pages: 118-121 Article number: 5481220 Language: English ISBN-13: 9780769540030 Document type: Conference article (CA) Conference name: 2010 Asia-Pacific Conference on Wearable Computing Systems, APWCS 2010 Conference date: April 17, 2010 - April 18, 2010 Conference location: Shenzhen, China Conference code: 80933 Sponsor: Intelligent Information Technology Application; Research Association Publisher: IEEE Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States Abstract: The storage of non-zero elements of sparse matrix in the linked lists can dispense with transpose operation in the multiplication process, because multiplication shall be conducted only for elements in the two sparse matrices whose line number and column number are the same and whose values are not zero. As a result, the number of multiplications will be reduced. In the meantime, the use of linked list to store the elements of matrix will cut back the times of scanning the matrix elements. The theoretical analysis and experimental results show that algorithm of Vector-linked list sparse matrix multiplication has greater time efficiency and needs less storage space. It will lay the foundation for research in the field of image processing. © 2010 IEEE.
