Hi Mike,

it would be very convenient if the name variable in h5read is not mandatory but has a default value NULL, in which case a list of valid dataset identifiers is automatically displayed via h5ls together with a message that a dataset needs to be specified. This is especially helpful for people new to HDF5, that don't that there is a separate 'h5ls'.

Best, Frederik
