Indexing into a matrix is a means of selecting or modifying a subset of elements from the matrix. MATLAB®has several indexing styles that are not only powerful and flexible, but also readable and expressive. Matrices are a core component of MATLAB for organizing and analyzing data, and index...

MATLAB Online에서 열기 Ran in: For matrix R, sort(R) sorts each column and indsort are row indices. To reproduce the sorted matrix, you can convert those row indices into linear indices. Here are a few ways to do that: 테마복사 R = rand(10,10) R = 10x10 0.3822 ...

(MATLAB) 我有一个N×N矩阵,A和一个行索引向量v.我想替换的对角线元素一个只为行中的一个被指定的v不使用for循环. 例如: N = 10; A = rand(N,N); %Random N x N matrix v = [1 4 6 9 10]; %vector of row indices %What I want to do but without a for loop: for i = 1:...
Can I perform logical indexing when the logical indexing matrix is smaller then the indexed matrix in MATLAB 7.0 (R14)?This is an error in the documentation for the LOGICAL function in MATLAB 7.0 (R14). The documentation should read as follows:
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] ...
This is exactly the way we would index elements of a matrix in linear algebra. 这正是我们在线性代数中索引矩阵元素的方法。 We can also slice NumPy arrays. 我们还可以切片NumPy数组。 Remember the indexing logic. 记住索引逻辑。 Start index is included but stop index is not,meaning that Python ...
