To create an array with four elements in a single row, separate the elements with either a comma , or a space. Another way to create a matrix is to use a function, such as ones , zeros , or rand. For example, create a 5-by-1 column vector of zeros. MATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function.

Multidimensional arrays are an extension of 2-D matrices and use additional subscripts for indexing. A 3-D array, for example, uses three subscripts. The first two are just like a matrix, but the third dimension represents pages or sheets of elements. You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array. Now add a second page.

Help Center Help Center. This can be helpful for preprocessing your data for subsequent computations or analyzing the data. The reshape function changes the size and shape of an array. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. As long as the number of elements in each shape are the same, you can reshape them into an array with any number of dimensions. Using the elements from A , create a 2-byby-3 multidimensional array.

For example, add a fourth page to B that contains all zeros. So the element at row 1 column 2 is, in fact, the fifth element stored. More Answers 0. But you can insert the elements, such that the array grows:. Up Next:. I have to insert a 3x1 matrix into a another matrix where this 3x1 matrix would be the first element of that matrix. A matrix is a two-dimensional array often used for linear algebra. Matrices and Arrays Array creation, combining, reshaping, rearranging, and indexing. You could use a cell array :. To access elements in a multidimensional array, use integer subscripts just as you would for vectors and matrices. You may receive emails, depending on your communication preferences. X1,X2 ,Xn , A are 1D arrays vector. For example, create a new 3-D array B by concatenating A with a third page.

A vector is a one-dimensional array and a matrix is a two-dimensional array. We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays.
