Dimensions of a Matrix. The number of rows and columns of a matrix, written in the form rowsÃcolumns. The matrix below has 2 rows and 3 columns, so its dimensions are 2Ã3. This is read aloud, two by three.. Note: One way to remember that R ows come first and C olumns come second is by thinking of RC Cola Â® .
Although matrices are two dimensional, they do not always appear to have a rectangular shape. A 1-by-8 matrix, for example, has two dimensions yet is linear. These matrices are described in the following sections: The Empty Matrix. An empty matrix has one or more dimensions that are equal to zero. A two-dimensional matrix with both dimensions equal to zero appears in the MATLAB Â® application as [] . The expression A = [] assigns a 0-by-0 empty matrix to A. Scalars. A scalar is 1-by-1 and appears in MATLAB as a single real or complex number (e.g., 7, 583.62, -3.51, 5.46097e-14, 83+4i).
