• The influence coefficient matrix method is one of the rapid solvers of the Poison equation and it is well known as the error vector propagation method. However, the method is limited in practice owing to its fatal defects, which take place in the application to a large domain and to a Neumann boundary condition. The defects are removed by some simple matrix calculations in this paper. Further, the present method is applied to the cavity flow as an example and then it is extended to solve the simultaneous partial differential equations concerning to the stream function and the vorticity with the particular boundary conditions. Consequently, the rapid numerical calculation of the cavity flow becomes available by the present method in the wide range of Reynolds numbers. In particular, it is made clear that the method is effective for the cavity flow of very low Reynolds numbers.
