What is the Julian equivalent of Python’s np.eye(5, 5, 1) % python -q >>> import numpy as np >>> np.eye(5, 5, 1) array([[0., 1., 0., 0., 0.], [0., 0., 1., 0., 0.], [0., 0., 0., 1., 0.], [0., 0., 0., 0., 1.], [0., 0., 0., 0., 0.]])

Probably using diagm() . In your case: diagm(1 => [1, 1, 1, 1]); If you want efficient data structure you may use BandedMatrices.jl . I am not aware of a data structure specialized for the case the diagonals have the values 0 or 1 (Namely no need for multiplication for Matrix Multiplication).
