1 引言 考虑如下的n×m范德蒙矩阵V1和跳行范德蒙矩阵V2
In this paper, a fast algorithm for the least squares solution of linear equations which coeficient matrices are Vandermonde-type matrix with full column rank is given by constructing a spel blocked matrix and utlizing fast triangular factorization of the matrix. In contrast with previous methods, new algorithms reduce operations or improve precision.
