7 Working with Scientific Data Formats
The return value contains the values in the data set, in this case a 1-by-10
vector of single-precision values:
data =
1.0000
1.1000
1.2000
1.3000
1.4000
1.5000
1.6000
1.7000
1.8000
1.9000
The hdf5read function maps HDF5 data types to appropriate MATLAB data
types, whenever possible. If the HDF5 file contains data types that cannot
be represented in MATLAB, hdf5write uses one of the predefined MATLAB
HDF5 data type objects to represent the data.
For example, if an HDF5 data set contains four array elements, hdf5read can
return the data as a 1-by-4 array of hdf5.h5array objects:
whos
Name Size Bytes Class
data 1x4 hdf5.h5array
Grand total is 4 elements using 0 bytes
For more information about the MATLAB HDF5 data type objects, see
“Mapping HDF5 Data Types to MATLAB Data Types” on page 7-18.
Exporting Data to HDF5 Files
To write data or metadata from the MATLAB workspace to an HDF5 file, use
the hdf5write function. As arguments, specify:
• Name of an existing HDF5 file, or the name you want to assign to a new file.
