Sample code needs to be updated.

[MooersLab]

The example in the Readme.md is not working with Python3.6. The k and l are 2-D numpy matrices that need to be converted to np.arrays before sending to matplotlib. In addition, the 'col' parameter name needs to be replaced with 'c' or 'color'.

import lhsmdu
import matplotlib.pyplot as plt
import numpy as np

k = lhsmdu.sample(2, 20) # Latin Hypercube Sampling with multi-dimensional uniformity
print(k)
l = lhsmdu.createRandomStandardUniformMatrix(2, 20) # Monte Carlo sampling

k = np.array(k)
l = np.array(l)

fig = plt.figure()
ax = fig.gca()
ax.set_xticks(np.arange(0,1,0.1))
ax.set_yticks(np.arange(0,1,0.1))
plt.scatter(k[0], k[1], color="g", label="LHS-MDU")
plt.scatter(l[0], l[1], color="r", label="MC")
plt.grid()
plt.show()

m = lhsmdu.resample()
n = lhsmdu.resample()
o = lhsmdu.resample()
m = np.array(m)
n = np.array(n)
o = np.array(o)

fig = plt.figure()
ax = fig.gca()
ax.set_xticks(np.arange(0,1,0.1))
ax.set_yticks(np.arange(0,1,0.1))
plt.title("LHS-MDU")
plt.scatter(k[0], k[1], c="g", label="sample 1")
plt.scatter(m[0], m[1], c="r", label="resample 2")
plt.scatter(n[0], n[1], c="b", label="resample 3")
plt.scatter(o[0], o[1], c="y", label="resample 4")
plt.grid()
plt.show()

Thanks, I've updated the README with these suggestions.

Closing issue.
