Abstract: Based on the distribution about eigenvalues of matrix，the approximately distributed region of matrix eigenvalues is determinated，using hybrid artificial fish school algorithm to solve approximate eigenvalues of matrix.Several experimental results show that the proposed hybrid artificial fish school algorithm is efficient in solving the matrix’s eigenvalues and can reach a certain precision.
