OFFSET
1,2
EXAMPLE
For every identity matrix of size n starting with n=1, append n*(each entry of each row of the matrix), e.g., n=1 -> 1, n=2 -> 2,0,0,2, so the first 5 terms of the sequence are 1,2,0,0,2.
PROG
(Python)
import numpy as np
def n_id_sequence(iterations):
sequence = []
for i in range(1, iterations+1):
matrix = i*(np.identity(i))
for row in matrix:
for entry in row:
sequence.append(int(entry))
return sequence
