Reading HDF Data

Description

Reads a dataset or attribute from the specified file. The argument file is a character row vector that specifies a valid HDF5 file. The argument object parent is a character row vector specifying a valid group or dataset in file file. The argument object name is a character row vector specifying the name of the dataset or attribute to read. If object name is a dataset, object parent must be a valid group, otherwise object parent may be either a group or dataset.

O-Matrix supports reading, writing, and creating HDF5 files. See the NCSA HDF 5 site for more information about HDF5, and a description of this file format.

Example

If you have an HDF5 file test.h5 that contains a dataset "vector", which is a three-element dataset that contains the value 1, and you enter
     h5read("test.h5", "/", "vector")
O-Matrix will respond
{
1
1
1
}
If the dataset "vector", contains a character attribute, "description", whose value is "My Data", and you enter
     h5read("test.h5","/vector","description")
O-Matrix will respond
My Data
