In this paper, the theoretical and numerical aspects of the generalized
Purcell method for solving a system of homogeneous linear equations
are provided. The novel row and the column pivoting are defined, that help toprove the stability of the method. The proposed method is generalized for solvingeigenvalue and eigenvector problems. The advantages of the method are:
 1.The presented method generates the set of linearly dependent rows of a matrix,say A, and its multiple independent solutions in solving
Ax = 0;
2.It gives the eigenvectors of a matrix A if there exists an eigenvalue with geometric multiplicity;
3. For a real and symmetric matrix it will gives an a posteriori error
estimation; and
 4. Also is proved that the complexity of the method is approximately
half of the complexity of the Gaussian elimination method. Finally, in
order to indicate the reliability and efficiency of the method, comparisons with the power method are made.
