## What is a matrix in MATLAB?

A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, or some other MATLAB data type.

**What is a specialized matrix function in MATLAB?**

Specialized Matrix Functions. MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the and functions create matrices of all zeros or all ones. The first and second arguments of these functions are the number of rows and number of columns of the matrix, respectively.

**How do you expand a matrix in MATLAB?**

Expanding a Matrix. You can add one or more elements to a matrix by placing them outside of the existing row and column index boundaries. MATLAB automatically pads the matrix with zeros to keep it rectangular. For example, create a 2-by-3 matrix and add an additional row and column to it by inserting an element in the (3,4) position.

### How do you construct a matrix of data?

Constructing a Matrix of Data. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements.

A matrix is a two-dimensional array of numbers. In MATLAB, you create a matrix by entering elements in each row as comma or space delimited numbers and using semicolons to mark the end of each row.

**What is the difference between a MATLAB variable and a matrix?**

All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra.

**What is MATLAB?**

MATLAB is an abbreviation for “matrix laboratory.” 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
