Summary
Computational simulation is essential for designing electromagnetic devices, predicting radar and sonar signatures, improving medical imaging, modeling advanced materials and larger molecular systems, and testing physical systems before they are built. These applications often require solving mathematical models that are far too large for direct calculation using standard methods, especially in realistic three-dimensional geometries. A major obstacle is that the computer representation of the underlying physical system can become an enormous array of numbers (known as a "matrix"), so large tha
