abstract = {An efficient method for solution of systems of linear
equations with many right hand sides is developed. The
right hand sides are assumed to depend smoothly on a
parameter. The equations are solved by an iterative method
and a linear least squares approximation is used as initial
guess. The work spent on the iterations is bounded
independently of the number of right hand sides. The method
is applied to the solution of Maxwell's equations of
electromagnetics in the frequency domain. The efficiency of
the method is illustrated by computing the monostatic radar
cross section around an aircraft model. }
