Determine if data space is simple
output = H5S.is_simple(space_id)
output = H5S.is_simple(space_id) returns
a positive value if the data space specified by space_id is
a simple data space, zero if it is not, and a negative value to indicate
failure.
Create a new data space and verify that it is simple.
dims = [100 200]; h5_dims = fliplr(dims); space_id = H5S.create_simple(2,h5_dims,h5_dims); val = H5S.is_simple(space_id);
Create a null data space and verify that it is not simple.
space_id = H5S.create('H5S_NULL');
val = H5S.is_simple(space_id);
