numpy.matrix() in Python

Last Updated : 09 Mar, 2022

This class returns a matrix from a string of data or array-like object. Matrix obtained is a specialised 2D array. Syntax :

numpy.matrix(data, dtype = None) :

Parameters :

data  : data needs to be array-like or string 
dtype : Data type of returned array.

Returns :

data interpreted as a matrix

Python

# Python Program illustrating
# numpy.matrix class

import numpy as geek

# string input
a = geek.matrix('1 2; 3 4')
print("Via string input : \n", a, "\n\n")

# array-like input
b = geek.matrix([[5, 6, 7], [4, 6]])
print("Via array-like input : \n", b)

Output :

Via string input : 
 [[1 2]
 [3 4]] 


Via array-like input : 
 [[[5, 6, 7] [4, 6]]]

NumPy Array in Python

NumPy (Numerical Python) is a powerful library for numerical computations in Python. It is commonly referred to multidimensional container that holds the same data type. It is the core data structure of the NumPy library and is optimized for numerical and scientific computation in Python. Table of C

Python - Matrix

A matrix is a way to organize numbers in a rectangular grid made up of rows and columns. We can assume it like a table, where:Rows go across (left to right)Columns go down (top to bottom)The size of a matrix is defined by the number of rows (m) and columns (n). If a matrix has 3 rows and 4 columns,
