Abstract : In this paper, we study the second approximate Matsumoto metric $F=\alpha+\beta+\beta^2/\alpha+\beta^3/\alpha^2$ on a manifold $M$. We prove that $F$ is of scalar flag curvature and isotropic S-curvature if and only if it is isotropic Berwald metric with almost isotropic flag curvature.
Keywords : isotropic Berwald curvature, S-curvature, almost isotropic flag curvature
