２行３列の行列を加算する (多次元配列)

Python

ma  = [[1, 2, 3], [4, 5, 6]]
mb  = [[6, 3, 4], [5, 1, 2]]
mc  = [[0, 0, 0], [0, 0, 0]]

for i in range(0, 2, 1):
    for j in range(0, 3, 1):
        print "%3d" % mc[i][j],
    print

for i in range(0, 2, 1):
    for j in range(0, 3, 1):
        mc[i][j] = ma[i][j] + mb[i][j]

for i in range(0, 2, 1):
    for j in range(0, 3, 1):
        print "%3d" % mc[i][j],
    print
