[FIXED] Creating matrix with the same vector in each row

Issue

I have p = [1,2,3,4]. I would like a 100x4 numpy matrix with p in each row. What's the best way to create that?

I tried pvect = np.array(p for i in range(10)) but that doesn't seem to be right.

Thanks

Solution

Use numpy.tile:

pvect = np.tile(p, (100, 1))

output:

array([[1, 2, 3, 4],
       [1, 2, 3, 4],
       ...
       [1, 2, 3, 4],
       [1, 2, 3, 4]])
