Examples

>>> import numpy as np
>>> from pydl.pydlutils.misc import struct_print
>>> struct_print(np.array([(1,2.34,'five'),(2,3.456,'seven'),(3,4.5678,'nine')],dtype=[('a','i4'),('bb','f4'),('ccc','S5')]),silent=True)
(['a bb          ccc  ', '- ----------- -----', '1        2.34 five ', '2       3.456 seven', '3      4.5678 nine '], [])
