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.

This is an error in the documentation for the LOGICAL function in MATLAB 7.0 (R14). The documentation should read as follows: 테마복사 When the logical indexing matrix is smaller than the indexed matrix, MATLAB expands the logical indexing matrix with...

I'm trying to index a large matrix, with the goal of finding/indexing the first value to meet a threshold. Right now I'm doing it in a loop, but it's rather slow. For example: a=[10 13 14 15 16;... 11 12 15 16 17;... 3 5 8 9 12]; threshold=11.5; I want it to ...
Aboutnot callingsubsasgn. I would love that. That is all I want. The matrix/vector indexing to be efficient as in the originalx(:)case. As a side note. Looking at the memory usage of MATLAB in system monitor I see that the memory consumption goes up by ~800MB when I execute...

I want to bootstrap this matrix. I have a matrix of indices INDX(nrep,M) with nrep the number of rows which correspond to the number of bootstrap draws, and M the number of of elements in each bootstrap draw. Each element of INDX picks an individual from the original dataset, and ...
(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:...
