ndarray, Grundsätzliches

ndarrays

• homogene mehrdimensionale Arrays
• Indiziert durch Tupel von positiven Integern

>>> v = np.array([32, 42, 99, 102])

>>> v

array([ 32, 42, 99, 102])

>>> p = np.array([ [ [12, 0, 3], [12, 1, 7], [24, 4, 9]],

... [ [13, 1, 5], [13, 2, 8], [15, 6, 8]],

... [ [12, 1, 4], [14, 5, 9], [24, 4, 3]]])

>>>

>>>

>>> p[0, 0]

array([12, 0, 3])

>>> p[0, 1]

array([12, 1, 7])

>>> p[1, 1]

array([13, 2, 8])
