Finding Toeplitz matrix using SciPy

Overview:

A Toeplitz matrix is a matrix whose diagonal elements are constant. i.e, The value of the diagonal elements are equal. Toeplitz matrix is named after the mathematician Otto Toeplitz.
Toeplitz matrices have their applications in several scientific fields including finding solutions to differential equations and integral equations, signal processing, image processing, spline functions and queuing theory.
Given the first colulmn and the first row of the output matrix, the function toeplitz() from the linalg module of the scipy library returns a Toeplitz matrix as an ndarray. If the first row is not given its is taken as the conjucate of the given first column.

# Example Python program that creates a
# Toeplitz matrix using the scipy module
# scipy.linalg

import scipy.linalg as sclg

firstColumn = [1, 3, 5]
firstRow = [1, 2, 4]

# Create a Toeplitz matrix with the given first column and
# the first row
toeplitzMatrix = sclg.toeplitz(firstColumn, firstRow)

print("First column:")
print(firstColumn)

print("First row:")
print(firstRow)

print("Toeplitz matrix:")
print(type(toeplitzMatrix))
print(toeplitzMatrix)

First column:
[1, 3, 5]
First row:
[1, 2, 4]
Toeplitz matrix:
<class 'numpy.ndarray'>
[[1 2 4]
[3 1 2]
[5 3 1]]
