In general, you can use indexing to access elements of any array in MATLAB regardless of its data type or dimensions. For example, directly access a column of adatetimearray. t = [datetime(2018,1:5,1); datetime(2019,1:5,1)]
Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. For example, consider the 4-by-4 matrixA: A = [1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16] ...

MATLAB also accepts logical indexing, which can be useful when working with conditional statements. For example, say you want to know the values of "A" that is larger than 7. Use the > operator to return a logical array whose elements are logical 1 when an el...

Array indexing数组索引 Numpy提供了几种索引数组的方法。 Slicing:与Python lists类似,numpy arrays 可以被切分。因为数组一定是多维的,你必须为数组的每一个维度确定一个切分。 import numpy as np #创建如下rank为2、shape为 (3, 4)的数组 # [[ 1 2 3 4] ...
