NumPy Matrix transpose() Python numpy module is mostly used to work with arrays in Python. We can use the transpose() function to get the transpose of an array. import numpy as np arr1 = np.array([[1, 2, 3], [4,
3],dtype=int)a = np.random.randint(0, 10, (4,3))y = np.array([4, 5, 6])np.diag(...
numpy.matrix.transpose 矩阵转置 Returns a view of the array with axes transposed. For a 1-D array, this has no effect. (To change between column and row vectors, first cast the 1-D array into a matrix object.) For a 2-D array, this is the usual matrix transpose. For an n-D arr...
In NumPy, we can obtain the transpose of a matrix using the np.transpose() function. For example, import numpy as np # create a matrix matrix1 = np.array([[1, 3], [5, 7]]) # get transpose of matrix1 result = np.transpose(matrix1) print(result) Output [[1 5] [3 7]] Here...

Transpose transpose is added in version 1.2 in order to transpose input matrix (only in Direct CM mode) Relabel relabel method is added in version 1.5 in order to change ConfusionMatrix classnames. >>> cm.relabel(mapping={0: "L1", 1: "L2", 2: "L3"}) >>> cm pycm.ConfusionMatrix(...
