HDF5 文件
高级访问函数使得易于从 HDF5 文件中读取和查看数据,或者将 MATLAB® 工作区中的变量写入 HDF5 文件。
可通过 HDF5 库程序包中的低级函数直接访问 HDF 组的 HDF5 C 库中的 300 多个函数。要创建或写入非数值数据集或属性,您必须使用低级函数。
要使用 MATLAB 低级 HDF5 函数,您必须熟悉 HDF5 C API 编程概念,如 The HDF Group 网站中所述。
MATLAB 支持 HDF5 版本 1.10.10。
函数
主题
- Import HDF5 Files
Read data from an HDF5 file using the high-level functions, the low-level functions, and the Import Data Live Editor task.
- Export to HDF5 Files
Write data and metadata from the MATLAB workspace to an HDF5 file.
- Work with Non-ASCII Characters in HDF5 Files
MATLAB supports non-ASCII data and metadata in HDF5 files.
- Read and Write Data Concurrently Using Single-Writer/Multiple-Reader (SWMR)
Write data to an HDF5 file in one process while you concurrently read from the file in one or more reader processes.
- Work with HDF5 Virtual Datasets (VDS)
Access data stored across multiple HDF5 files as a single, unified HDF5 dataset.
- Read and Write HDF5 Datasets Using Dynamically Loaded Filters
The HDF5 library and file format enables using filters on data chunks before they are written to or after they are read from disk.
