Simulations of four rotation methods.

(a) The average number of sweeps versus array sizes

(b) The number of shift-add operations versus array sizes

(c) The required number of sweeps versus array off-diagonal norm (80×80 array with double precision)

(d) The required number of sweeps versus array off-diagonal norm (80×80 array with single precision)
