abstract = {The Minimal Residual Interpolation method reduces the
number of iterations in an iterative method for multiple
right hand sides. It uses computed solutions to initialize
an iterative solver with an accurate guess. This paper
demonstrates the efficiency of the method for frequency
sweeps and solving scattering problems by plane waves
incident from multiple angles. A bound on the number of
solutions required for plane wave scattering before the
remaining solutions are obtained by Minimal Residual
Interpolation only is given. We discuss the performance of
the method compared to iterative seed techniques. In a
numerical example a reduction factor of $60$ is obtained on
the number of matrix vector multiplications.}
