A conventional method of shifting machine's tune close to a difference resonance to obtain approximately round beams is usually analyzed with perturbation theories. In this paper, we adopt the Solution by LInear Matrices (SLIM) analysis to exactly calculate beam sizes when the linear coupling is present. The SLIM analysis can deal with a generally linearly coupled accelerator lattice,

Both the on- and off-resonance schemes to obtain round beams are explained with examples. The formalism for two magnet models, combined-function bending magnets, planar wigglers and undulators, which are widely used on light source storage rings, are derived.
