The Oberwolfach Steel-Profile benchmark revisited

This archive features the matrix data for the reimplemented Steel Profile benchmark from the Oberwolfach Collection. In contrast to the original, it uses FENICS, rather than ALBERTA, for the finite element semi-discretization in space. Download and unzip all ZIP files for the dimensions you need (numbers in the names are dimensions of the system) add getrail.m to the same folder download mmread.m from https://math.nist.gov/MatrixMarket/mmio/matlab/mmiomatlab.html See `help getrail` for usage instructions.本归档文件包含源自奥伯沃尔夫赫馆藏基准集（Oberwolfach Collection）的重实现版钢型材基准测试的矩阵数据。与原始版本不同，本数据集在空间域的有限元半离散化过程中采用了FENICS而非ALBERTA工具包。请下载并解压您所需维度对应的所有ZIP压缩包（文件名中的数字代表该系统的维度），将getrail.m文件添加至同一文件夹中，再从https://math.nist.gov/MatrixMarket/mmio/matlab/mmiomatlab.html 下载mmread.m文件。可通过`help getrail`命令查看使用说明。
