MATLAB is an abbreviation for matrix laboratory. While other programming languages mostly work with numbers one at a time, MATLABÂ® is designed to operate primarily on whole matrices and arrays. All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra. Array Creation To create an array with four elements in a single row, separate the elements with either a comma (,) or a space.
