Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (.) distinguishes the array operations from the matrix operations.

To create an array with four elements in a single row, separate the elements with either a comma (,) or a space. This type of array is a row vector. To create a matrix that has multiple rows, separate the rows with semicolons. 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 vect...
MATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function. To transpose a matrix, use a single quote ('): You can perform standard matrix multiplication, which computes the inner products between rows and columns, using the *operator. For example, confirm that a matrix times its inverse returns the id...
Concatenation is the process of joining arrays to make larger ones. In fact, you made your first array by concatenating its individual elements. The pair of square brackets is the concatenation operator. Concatenating arrays next to one another using commas is called horizontal concatenation. Each array must have the same number of rows. Similarly,...
Complex numbers have both real and imaginary parts, where the imaginary unit is the square root of -1. To represent the imaginary part of complex numbers, use either i or j.
Jul 29, 2014 · All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra. source: https://www.mathworks.com/help/matlab/learn_matlab/matrices-and-arrays.html.
Mar 12, 2015 · A matrix is a practical way to represent a linear transformation from a space of dimension n to a space of dimension m in the form of a nxm array of scalar values. It is also very practical to perform linear algebra operation in a very systematic way that can be implemented on a computer.
Dec 27, 2023 · A matrix in MATLAB refers to a special case of a 2D array with rows and columns optimized for mathematical operations. Example 2×3 matrix: A = [1.5, 4, 2; . 5, 3, 6]; Matrix attributes: Strictly a 2D structure with rows and columns. Exclusively stores numeric data. Enables specialized math functions like inverse, eigen decomposition etc.
While other programming languages mostly work with numbers one at a time, MATLAB® 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.

The above is a 2D array or matrix. A 1D array is called a vector. arr_1D = [1 2 3 4 5 6 7 8 9] We can also have 3D, as well as, ND arrays. In case of a 3D array, imagine a Rubik’s cube with each cell having a value inside it. Here is and example using MATLAB "rand" function >> Arr_3D = rand (2,2,2) Arr_3D (:,:,1) =.
