numpy.matrix() in Python (original) (raw)

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

import numpy as geek

a = geek.matrix( '1 2; 3 4' )

print ( "Via string input : \n" , a, "\n\n" )

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]]]
