Test Display Functions¶

Functions are ... Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

def function_name(arg_1, arg_2):
    pass

Write the functions like this

In [5]:

def my_function(arg_1):
    print("arg_1 is: {}".format(arg_1))

Then call them like this

In [6]:

my_function("test")

arg_1 is: test

import numpy as np

import matplotlib
import matplotlib.pyplot as plt

import matplotlib.image as mpimg

In [8]:

x = np.linspace(0, 5, 100)
len(x)

Out[8]:

In [9]:

# Linear Function (f(x) = y = x)
x1 = x
y1 = x1

In [10]:

# Quadratic Function (f(x) = y = x^2)
x2 = x
y2 = x**2

In [11]:

# Cubic Function (f(x) = y = x^3)
x3 = x
y3 = x**3

Then plot each of the functions

In [12]:

# A figure with one axes and three functions (MATLAB-style)
plt.plot(x1, y1, label='linear')
plt.plot(x2, y2, label='quadratic')
plt.plot(x3, y3, label='cubic')

plt.xlabel('x values')
plt.ylabel('y values')

plt.title("Three Function Plot")

plt.legend()

print('Current Axes: {}'.format(plt.gca()))
print('Current Figure: {}'.format(plt.gcf()))

Current Axes: AxesSubplot(0.125,0.125;0.775x0.755)
Current Figure: Figure(432x288)

In [11]:

img_fox = mpimg.imread('img/fox.png')
print('Image Shape: {}'.format(img_fox.shape))
plt.imshow(img_fox)

Image Shape: (681, 1024, 3)
