fliplr 水平翻转数组(axis=1)。 备注 flip(m, 0) 等同于 flipud(m)。 flip(m, 1) 等同于 fliplr(m)。 flip(m, n) 对应于在位置 n 上使用::-1的m[...,::-1,...]。 flip(m) 对应于在所有位置上使用::-1的m[::-1,::-1,...,::-1]。 flip(m, (0, 1)) 对应于在位置 0 和位...

Numpy fast check for complete array equality, like Matlabs isequal, Testing the equality of two numpy 2d arrays, Check how many numpy array within a numpy array are equal to other numpy arrays within another numpy array of different size, How to test if
If we set axis to 1, we get an error in the output as axis=1 indicates joining along the second dimension, i.e., along the rows, which doesn’t exist. Let’s check out the output for the above code: [12 23 34 45 56 67] Next, let’s set the axis parameter to 1 in the ...
Consider two random array A and B, check if they are equal # 如果两个数组在公差范围内按元素方式相等,则返回True。 # 公差值是正的,通常很小。将相对差(rtol * abs(b))和绝对差atol相加在一起,以与a和b之间的绝对差进行比较。 # 如果任一数组包含一个或多个NaN,则返回False。如果两个数组中的...
