import numpy #numpy1.y
a= numpy.array([1,2,3,4]) #membuat matriks 4x1
print('a=')
print(a)


#membuat 2 matriks 2x2:
b=numpy.array ([[1,2],
                           [3,4]])
print('b=')
print(b)

c=numpy.array ([[3,4],
                           [5,6]])
print('c=')
print(c)

#penjumlahan matriks
d=b+c
print('d=')
print(d)

#dot product
e=numpy.dot(b,c)
print('e=')
print(e)
