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. However, before that, let us discuss some special types of arrays. In this section, we will discuss some functions that create some special arrays.

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 also access elements with what is known as logical indexing where you specify an indexing array of equal size filled with true or false values, like a mask. Reshaping a multidimensional array can be useful for performing certain operations or visualizing the data. For example, raise each element of a to the third power:. We can also use the cat function to build multidimensional arrays. In a matrix, the two dimensions are represented by rows and columns.

Sometimes it is convenient to treat two dimensional arrays such as these as a one dimensional array as though all the columns were stacked together into a single column and specify single index. Trial Software Trial Software. You can see information about all indexing techniques in the documentation. You can change the rows to columns with the transpose operator. Reshaping and Rearranging Arrays Change the shape or arrangement of elements in an existing array.
