The simplest approach is to go with a dictionary:
>>> matrix = {}
>>> arinc = ['ab', '2b', '0b']
>>> pids = [300, 321]
>>> for x in arinc:
... for y in pids:
... matrix[x, y] = y + int(x, 16) # replace with your actual data
...
>>> matrix
{('ab', 300): 471, ('2b', 300): 343, ('ab', 321): 492, ('0b', 321): 332,
('2b', 321): 364, ('0b', 300): 311}
Get one entry:
>>> matrix["2b", 321]
364
Get all items along an axis:
>>> [matrix[x, 300] for x in arinc]
[471, 343, 311]
