Routine Name: addvectors
Author: Tanner Wheeler
Language: Python. This code can be run on a python 3 compiler. The file can be imported and then the method will run.
Description/Purpose: This method will add two vectors of the same length together and create a new vector from their addition.
Input: There are two inputs for this method. Both are vectors of the same length, but may contain different values.
Output: This will return the new vector that is the addition of the input vectors.
Usage/Example: First let’s create two vectors c and d of size 3 and set each element to a specific number.
c = [float(0) for i in range(0, 3)]
d = [float(0) for i in range(0, 3)]
c[0] = 1.5
c[1] = 9.4
c[2] = 3.3
d[0] = 1
d[1] = 9
d[2] = 3
Now let’s print out the value return from our function given our created vectors.
print(addvectors(c, d))
This will print
[2.5, 18.4, 6.3]
to the console.
Implementation/Code: The following is the code for addvectors(x, y)
def addvectors(x, y):
if len(x) != len(y):
return "Error inconsistent lengths!"
newVector = [0 for i in range(0, len(x))]
for i in range(0, len(x)):
newVector[i] = x[i] + y[i]
return newVector
