H5SIZE get shape of HDF5 variable

Contents

Inputs

filename: data filename variable: name of variable inside file

Outputs

fsize: vector of variable size per dimension. Empty if scalar variable.

function fsize = h5size(file, variable)
arguments
  file (1,1) string
  variable (1,1) string
end

dsi = h5info(file, variable).Dataspace;

if ~stdlib.isoctave() && dsi.Type == "scalar"
  fsize = [];
else
  fsize = dsi.Size;
end

end
