- MATLAB combines a desktop environment tuned for iterative analysis and design processes with a programming language that expresses matrix and array mathematics directly. It includes the Live Editor for creating scripts that combine code, output, and formatted text in an executable notebook.
- Apr 14, 2014 A B returns a logical array with elements set to logical 1 (true) where arrays A and B are equal; otherwise, the element is logical 0 (false). The test compares both real and imaginary parts of numeric arrays. Eq returns logical 0 (false) where A or B have NaN or undefined categorical 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.
For example, let us create a 4-by-5 matrix a −
MATLAB will execute the above statement and return the following result −
Referencing the Elements of a Matrix
To reference an element in the mth row and nth column, of a matrix mx, we write −
For example, to refer to the element in the 2nd row and 5th column, of the matrix a, as created in the last section, we type −
MATLAB will execute the above statement and return the following result −
To reference all the elements in the mth column we type A(:,m).
Let us create a column vector v, from the elements of the 4th row of the matrix a −
MATLAB will execute the above statement and return the following result −
You can also select the elements in the mth through nth columns, for this we write −
Let us create a smaller matrix taking the elements from the second and third columns −
MATLAB will execute the above statement and return the following result −
In the same way, you can create a sub-matrix taking a sub-part of a matrix.
MATLAB will execute the above statement and return the following result −
In the same way, you can create a sub-matrix taking a sub-part of a matrix.
For example, let us create a sub-matrix sa taking the inner subpart of a −
To do this, write −
MATLAB will execute the above statement and return the following result −
Deleting a Row or a Column in a Matrix
You can delete an entire row or column of a matrix by assigning an empty set of square braces [] to that row or column. Basically, [] denotes an empty array.
For example, let us delete the fourth row of a −
MATLAB will execute the above statement and return the following result −
Next, let us delete the fifth column of a −
MATLAB will execute the above statement and return the following result −
Example
In this example, let us create a 3-by-3 matrix m, then we will copy the second and third rows of this matrix twice to create a 4-by-3 matrix.
Create a script file with the following code −
When you run the file, it displays the following result −
Matrix Operations
In this section, let us discuss the following basic and commonly used matrix operations −

MATLAB is a programming language developed by MathWorks. It started out as a matrix programming language where linear algebra programming was simple. It can be run both under interactive sessions and as a batch job. This tutorial gives you aggressively a gentle introduction of MATLAB programming language. It is designed to give students fluency in MATLAB programming language. Problem-based MATLAB examples have been given in simple and easy way to make your learning fast and effective.
This tutorial has been prepared for the beginners to help them understand basic to advanced functionality of MATLAB. After completing this tutorial you will find yourself at a moderate level of expertise in using MATLAB from where you can take yourself to next levels.
Matlab Legend
We assume you have a little knowledge of any computer programming and understand concepts like variables, constants, expression, statements, etc. If you have done programming in any other high-level programming language like C, C++ or Java, then it will be very much beneficial and learning MATLAB will be like a fun for you.
