# 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]]]
