# Goal for next few classes: draw Julia sets for quadratic polynomials f(z)=z^2 + c
# c a complex number
# will represent complex plane as grid of points
# grid will be an array/matrix of 0s and 1s
import numpy # python package that has lots of useful math stuff
numpy.zeros((3,4)) # 3 rows, 4 columns
a=numpy.zeros((3,4))
a[2,1]=1
a
matrix_plot(a)
# we'll represent complex plane as large grid (600x600)
