Prerequisite: Linear Algebra | Defining a Vector

Linear algebra is the branch of mathematics concerning linear equations by using vector spaces and through matrices. In other words, a vector is a matrix in n-dimensional space with only one column. In the sequence of learning linear algebra using python, this is article 4. In some of the problems, we need to use a particular component of the vector.

For example: Let a vector a = [4, 9, 7], this is a 3 dimensional vector (x,y and z)

So, if we need to call the y^th component of the vector, we are talking about the corresponding value 9. 

In the python code, we will first define a vector and then we will call its 4^th component.

Python code for calling i^th dimensional Component of Vector

# Vectors in Linear Algebra
a = [3, 5, -5, 8]

print("Vector a = ", a)
# This is a 4-dimensional vector

i = int(input("type dimensional component you want to know: "))
print("Vector's", i," dimensional component = ", a[i-1])

Output

Vector a =  [3, 5, -5, 8]
type dimensional component you want to know: 4
Vector's 4  dimensional component =  8
