摘要：

A　matrix-number　inequality　theory　is　proposed　in　this　paper.　Utilizing　this　theory,　the　data　dynamic　range　for　a　famous　DCT　and　IDCT　algorithm　is　further　determined.　Employing　the　conclusion　drawn　from　this　dynamic　range　determination　process,　the　average　mean　square　error　for　its　IDCT　algorithm　is　decreased　from　0.029422　to　0.014714.　The　proposed　matrix-number　inequality　theory　is　applicable　to　any　fast　transform.　©　2005　IEEE.
