Anda dapat menggunakan metode berikut untuk membuat matriks NumPy dengan bilangan acak:<\/span><\/p>\n

Metode 1: Buat matriks NumPy dari bilangan bulat acak<\/strong><\/span><\/p>\n

 n.p. random<\/span> . randint<\/span> (low, high, (rows, columns))\n<\/strong><\/pre>\n
 Metode 2: Buat Matriks NumPy dari Float Acak<\/strong><\/span><\/p>\n
 n.p. random<\/span> . rand<\/span> (rows, columns)<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode dalam praktik.<\/span><\/p>\n
 Contoh 1: Buat matriks NumPy dari bilangan bulat acak<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara membuat matriks NumPy nilai acak berkisar antara 0<\/strong> sampai 20<\/strong> dengan bentuk 7 baris<\/strong> dan 2 kolom<\/strong> :<\/span><\/p>\n
 import<\/span> numpy as<\/span> np\n\n#create NumPy matrix of random integers\n<\/span>n.p. random<\/span> . randint<\/span> (0, 20, (7, 2))\n\narray([[ 3, 7],\n       [17, 10],\n       [0, 10],\n       [13, 16],\n       [6, 14],\n       [8, 7],\n       [9, 15]])<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa setiap nilai matriks berada antara 0 dan 20 dan bentuk akhir matriksnya adalah 7 baris dan 2 kolom.<\/span><\/p>\n
 Contoh 2:<\/strong><\/span> Buat matriks NumPy dari float acak<\/strong><\/h3>\n
 Kode berikut menunjukkan cara membuat matriks NumPy dengan nilai float acak antara 0<\/strong> dan 1<\/strong> dan berbentuk 7<\/strong> kolom dan 2<\/strong> baris:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np\n\n#create NumPy matrix of random floats\n<\/span>n.p. random<\/span> . rand<\/span> (7, 2)\n\narray([[0.64987774, 0.60099292],\n       [0.13626106, 0.1859029 ],\n       [0.77007972, 0.65179164],\n       [0.33524707, 0.46201819],\n       [0.1683, 0.72960909],\n       [0.76117417, 0.37212974],\n       [0.18879731, 0.65723325]])\n<\/span><\/span><\/strong><\/pre>\n
 Hasilnya adalah matriks NumPy yang berisi nilai float acak antara 0 dan 1 dengan bentuk 7 baris dan 2 kolom.<\/span><\/p>\n
 Perhatikan bahwa Anda juga dapat menggunakan fungsi NumPy round()<\/strong> untuk membulatkan setiap float ke sejumlah tempat desimal tertentu.<\/span><\/p>\n
 Misalnya, kode berikut menunjukkan cara membuat matriks NumPy dari float acak, masing-masing dibulatkan menjadi 2 tempat desimal:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np\n\n#create NumPy matrix of random floats rounded to 2 decimal places\n<\/span>n.p. round<\/span> (np. random<\/span> . rand<\/span> (5, 2), 2)\n\narray([[0.37, 0.63],\n       [0.51, 0.68],\n       [0.23, 0.98],\n       [0.62, 0.46],\n       [0.02, 0.94]])\n<\/span><\/span><\/strong><\/pre>\n
