The mult iresolut ion analy sis ( MRA) in computat ional elect romagnet ics is discussed systemat ically . Based on the mult ir esolution pro perty o f the base funct io n and the dif ferent t ransformation between base funct ions, the classificat ion of differ ent metho ds is given w hich rev eals the essence and r elat ionship of the differ ent methods. At the same t ime, the classification provides the clue to dev elo ping new appro ach, fo r example, f rom the fr ame of the MRA, a new numerical method-w avelet based mult igr id metho d is proposed by the authors. Finally , the comparison betw een tw o appro aches for so lving an oper ato r equat ion by using w avelet t ransfo rm is presented.
