of the same dimension(they are measurements of intervals, so they must be kinda stable). The simplest form just picks out a single element: A(2,4) Extract the element in row2, column 4 ans 8 More generally, one or both of the row and column subscripts can be vectors: A(2:4,1:2) ans A single : in a subscript position is shorthand. Ok, so how do you place elements of one array into another array, so that they are included in either the beginning of the array or the end of the array? However, on the left side of an assignment statement, you can specify elements outside the current dimensions. This is my array which is simply the intervals between data in this other array. Regular newsgroup contributor Peter Acklam posted this solution that uses sub2ind and linear indexing: index vectors for rows and columns memorias p 1:m; q 1:n; index matrices for rows and columns P, Q ndgrid(p, q create a matrix with the shift values K repmat(k. Here are the elements of the matrix A along with their linear indices: The linear index of each element is shown in the upper left. The vector is: v ; The subscript can be a single value : v(3) Extract the third element ans. Select web site You can also select a web site from the following list: How to Get Best Site Performance Select the China site (in Chinese or English) for best site performance. Indexing Vectors, let's start with the simple case of a vector and a single subscript. You can even do arithmetic using end : v(2: end -1) Extract the second through the next-to-last elements ans. Matlab users often hear: vectorization. Str(isspace(str) Logical indexing is closely related to the find function. Or the subscript can itself be another vector: v(1 5 6) Extract the first, fifth, and sixth elements ans 16. Americas Europe Asia para Pacific Contact your local office.

Indexing is also closely related to another term. Indexing into a matrix dating is a means of selecting a subset of elements from the madrid matrix. You can also select a web site from the following list.
Punnag, you can put Answers down below in the Answers section rather than up here.Though, I doubt there s a need to post a duplicate of the answer down there that was already posted 4 months ago.
Logical indexing, a3 ans The colon operator also allows you to create an equally spaced vector of values using the more general form start. Is to use a single subscript that traverses down each column in matlab put value at end of array order 16 2 B zerossizeA Bsub2indsizeA 1 1 2 4 ans 2 7 16 Aidx ans 5 7 1 Advanced Examples Using Linear Indexing Example. Less common, other MathWorks country sites are not optimized for visits from your location 4 Extract and swap the halves. The expression AA 5 is equivalent to AfindA. Based on your location, length,. Using a single subscript to refer to a particular element in an array is called linear indexing. Suitability, swap the two halves of v to make a new vector.
