WebWe present a Gear-type code that efficiently solves ordinary differential equations in large grid-domains. To obtain the final code, we modified an original program of C.W. Gear, built and added a sparse-matrix package, and vectorized all loops about the grid-cell dimension. Furthermore, to obtain at least 90% vectorization potential while preventing equations in …
