This paper introduces the basic theory of wavelet decomposition and reconstruction,and gives a new algorithm of multi-resolution editing of B-spline curves.The algorithm uses the wavelet decomposition and reconstruction in multi-resolution editing B-spline curves and transforms a zonal matrix or sparse matrix to a row simplified matrix using the properties of the augmented matrix of the system of linear equations,which is a zonal matrix or sparse matrix,by elementary row operation.Solve the system of linear equations.The algorithm makes the process of wavelet decomposition and reconstruction nice and quick.It is easy to be understood and accepted for engineers.
