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...

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 ...

they are actually stored in memory as a single column of elements. A good way to visualize this concept is with a matrix. While the following array is displayed as a 3-by-3 matrix, MATLAB stores it as a single column made up of the columns ofAappended one after the other. The stored...
