MATLAB Online에서 열기 Ran in: Hello Nordine and Simeon, I believe you are both experiencing the same error as the user inthis question. In short, MATLAB thinks you are trying to do indexing into an array when you did not intend to. I will try to illustrate what I...
Another approach for accessing elements of an array is to use only a single index, regardless of the size or dimensions of the array. This approach is known aslinear indexing. While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a si...
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)...

To apply linear indexing, the code generator must cast an N-dimensional array into a one-dimensional array. Casting operations make your code more complex for the code generator to analyze. This increased complexity can hinder the ability of the code generator to optimize for performance. ...

So I can take my previous list, 0, 2, 3, turn that into a NumPy array,and I can still do my indexing. 所以我可以把我以前的列表,0,2,3,变成一个NumPy数组,我仍然可以做我的索引。 In other words, we can index NumPy arrays 换句话说,我们可以索引NumPy数组 using either lists or other Nu...
