Abstract: A simple numerical algorithm on the spectral radius of irreducibly nonnegative matrix is given with the matrix diagonally similar change and PerronFrobenius Theorem. The algorithm is similar to a classical onepower method to calculate the largest matrix eigenvalue by module, which can be applied to any irreducibly nonnegative matrix, and will be quick and easy by choosing parameters properly.

Key words: irreducibly nonnegative matrix, spectral radius, algorithm, diagonally similar change
