Question : Make Rotation matrix in Python
Answered by : bad-buffalo-ptqj9zlumfad
In [x]: theta = np.radians(30)
In [x]: c, s = np.cos(theta), np.sin(theta)
In [x]: R = np.array(((c, -s), (s, c)))
Out[x]: print(R)

def rotate(matrix): rows = len(matrix) cols = len(matrix[0]) res = [] for i in range(cols): temp = [] for j in range(rows): temp.append(matrix[j][i]) res.append(temp[::-1]) return res
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
print(rotate(matrix))Source : | Last Update : Sat, 19 Mar 22
