In this paper, we study the shift and invert Arnoldi method has been popularly used for computing a number of eigenvalues clase to a given shift. We have developed the shift and invert method with a block matrix method for finding the eigenalues of equation AX-cBX in distinguish interval with high accuracy.

Block matrix, Generalized eigenvalue
