Bagaimana Anda mendefinisikan matriks 3 3 dengan python?

Matriks tidak lain adalah susunan persegi panjang dari data atau angka. Dengan kata lain, itu adalah array persegi panjang dari data atau angka. Entri horizontal dalam matriks disebut sebagai 'baris' sedangkan entri vertikal disebut sebagai 'kolom'. Jika suatu matriks memiliki r banyaknya baris dan c banyaknya kolom maka ordo matriks tersebut adalah r x c. Setiap entri dalam matriks dapat berupa bilangan bulat, atau nilai mengambang, atau bahkan bilangan kompleks

Contoh

// 3 x 4 matrix
     1 2 3 4
M =  4 5 6 7
     6 7 8 9

// 2 x 3 matrix in Python
A = ( [ 2, 5, 7 ],
      [ 4, 7, 9 ] )

// 3 x 4 matrix in Python where entries are floating numbers
B = ( [ 1.0, 3.5, 5.4, 7.9 ],
      [ 9.0, 2.5, 4.2, 3.6 ],
      [ 1.5, 3.2, 1.6, 6.5 ] )

Di Python, kita dapat mengambil matriks masukan pengguna dengan berbagai cara. Beberapa metode untuk matriks input pengguna dengan Python ditunjukkan di bawah ini

Kode #2. Menggunakan fungsi input7 dan input8

Di Python, ada perpustakaan populer bernama NumPy. Perpustakaan ini adalah perpustakaan dasar untuk perhitungan ilmiah apa pun. Ini juga digunakan untuk array multidimensi dan seperti yang kita ketahui matriks adalah array persegi panjang, kita akan menggunakan pustaka ini untuk matriks input pengguna
