abstractsMeshless methods are recently developed numerical methods which require only node informa- tion. This paper introduces the basic principles and history of meshless methods, the principles and implementation of the moving least square method taking Galerkin method as an example. Finite points mixed method (FPMM) and its application in solving electrocardiogram(ECG) forward problem is also introduced. Foreground and problems need to be solved concerning the application of meshless methods in the study of ECG forward problem are discussed.
