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 a datetime array. Get t = [datetime(2018,1:5,1); datetime(2019,1:5,1)] t = 2x5 datetime 01-Jan-2018 01-Feb-2018 01...
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 matrix A: Get A = [1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16]...
Many MATLAB functions that start withisreturn logical arrays and are very useful for logical indexing. For example, you could replace all the NaN elements in an array with another value by using a combination ofisnan, logical indexing, and scalar expansion with one line of code. B(isnan(B)...

In this example, index or ind, was defined as aPythonlist,but we could also have defined that as a NumPy array. 在本例中,index或ind被定义为Python列表,但我们也可以将其定义为NumPy数组。 So I can take my previous list, 0, 2, 3, turn that into a NumPy array,and I can still do my...

In MATLAB execution, if you grow a scalar array by using (end+1) indexing, the array grows along the second dimension and produces a row vector. For example, define the function grow: function z = grow(n, m) n(end+1) = m; z = n; end Call grow with example inputs: grow(2,...
