! The following example shows how to write and read to/from an existing dataset.
|
|
! It opens the file created in the previous example, obtains the dataset
|
|
! identifier, writes the data to the dataset in the file,
|
|
! then reads the dataset to memory.
|
|
!
|
|
! This example is used in the HDF5 Tutorial.
