热模型matlab代码随机建模和 UQ 最终项目 用于 UQ 类罕见事件估计的 MFCE 的最终项目。 “稳态热传导中罕见事件的多保真交叉熵估计” 作者:弗雷德里克·劳和泰伦斯·阿尔苏普 代码说明。 大多数 Matlab 函数和脚本都包含在名为“code”的目录中。 主要的Matlab文件是: 交叉熵 MFCE.m CE_LogNormal.m MFCE_LogNormal.m 文件 1. 和 2. 使用一系列高斯偏置密度实现 CE 和 MFCE。 文件 3. 和 4. 使用一系列对数正态偏置密度实现 CE 和 MFCE。 要了解如何运行代码,请查看这些文件的文档。 “ellip”目录包含用于划分域和使用有限元求解 PDE 所需的函数和文件。 我们测试运行的数据包含在“sim data”目录中。 一些测试用例包含了几个额外的 Matlab 脚本。 以下是用于生成数据和绘图的函数和脚本的一些快速说明。 CE_biasing_density.m - 绘制从交叉熵中找到的偏置密度以及最佳偏置密度。 sqcov_plot.m -- 读取模拟数据以制作 MFCE 和 CE SQCoV 与运行时的
