Array of arrays matlab

Help Center Help Center. In a matrix, the two dimensions are represented by rows and columns. Each element is defined by two subscripts, the row index and the column index. 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. To do this, assign another 3-by-3 matrix to the index value 2 in the third dimension. The syntax A :,:,2 uses a colon in the first and second dimensions to include all rows and all columns from the right-hand side of the assignment. The cat function can be a useful tool for building multidimensional arrays.

Help Center Help Center. A matrix is a two-dimensional array often used for linear algebra. 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. For example, confirm that a matrix times its inverse returns the identity matrix:.

A MATLAB array can be one-dimensional, in which case it is called a vector , two-dimensional, in which case it is called a matrix , or higher-dimensional. This book will not deal with array dimensions higher than 2. Initially, we will consider arrays of numbers; later we will introduce arrays of characters and strings. The dimensions of an array are expressed as number of rows X number of columns. The most explicit way to create a vector is to list the numbers in square brackets, separated by commas, spaces or semi-colons.
