h5read

Read the data of HDF5 dataset

Calling Sequence

h5read(obj [, name, [, start, count [, stride [, block]]]])
h5read(filename, name [, start, count [, stride [, block]])

Arguments

obj

a H5Object

name

a string giving the path to the new dataset

start

a row of doubles containing the start of the hyperslab

count

a row of doubles containing the count of the hyperslab

stride

a row of doubles containing the stride of the hyperslab

block

a row of doubles containing the block of the hyperslab

filename

a string giving the filename

Description

Read the content of a dataset according to the optional hyperslab selection.

It is possible to make an hyperslab selection on the data.

The arguments start, count, stride and block must have a size equal to the number of dimensions of the data:

  • start: gives the coordinates in the data where to start the selection.
  • count: gives the number of selected blocks in each dimension.
  • stride: gives the shift between two consecutives blocks in each dimension. Take care that the stride must be greater than the corresponding block dimension.
  • block: gives the block dimensions.

By default stride and block are set to 1 in each dimension.

Examples

x = int8(matrix(1:80, 10, 8));
save(TMPDIR + "/x.sod", "x"); // SOD files are HDF5 ones

// Open the created file
a = h5open(TMPDIR + "/x.sod");

// Read the data from the dataset 'x'
dx = h5read(a, "/x")

// Now select a part
dx1 = h5read(a, "/x", [3 4], [5 3])

// ...which is equivalent to
dx(3:(3+5-1),4:(4+3-1))

// We have finished so we free all the resources
h5close(a);
