MATLAB supports various numeric classes that include signed and unsigned integers and single-precision and double-precision floating-point numbers. By default, MATLAB stores all numeric values as double-precision floating point numbers. You can choose to store any number or array of numbers as

The colon(:) is one of the most useful operator in MATLAB. It is used to create vectors, subscript arrays, and specify for iterations. If you want to create a row vector, containing integers from 1 to 10, you write − Live Demo 1:10 MATLAB executes the statement and returns a row vect

All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array. We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some

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 − Live Demo a = [ 1 2 3 4 5; 2 3 4 5 6; 3

A vector is a one-dimensional array of numbers. MATLAB allows creating two types of vectors − Row vectors Column vectors Row Vectors Row vectors are created by enclosing the set of elements in square brackets, using space or comma to delimit the elements. Live Demo r = [7 8 9 10 11]

There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially. The first statement in a function is executed first, followed by the second, and so on. Programming languages provide various control structures that allo

Decision making structures require that the programmer should specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. MATLAB is designed to operate primarily on whole matrices and arrays. Therefore, operators in MATLAB work both on scalar and non-scalar data. MATLAB allows the following types of elementar

MATLAB does not require any type declaration or dimension statements. Whenever MATLAB encounters a new variable name, it creates the variable and allocates appropriate memory space. If the variable already exists, then MATLAB replaces the original content with new content and allocates new stor

So far, we have used MATLAB environment as a calculator. However, MATLAB is also a powerful programming language, as well as an interactive computational environment. In previous chapters, you have learned how to enter commands from the MATLAB command prompt. MATLAB also allows you to write ser

MATLAB is an interactive program for numerical computation and data visualization. You can enter a command by typing it at the MATLAB prompt >> on the Command Window. In this section, we will provide lists of commonly used general MATLAB commands. Commands for Managing a Session MATLAB pr

In MATLAB environment, every variable is an array or matrix. You can assign variables in a simple way. For example, Live Demo x = 3 % defining x and initializing it with a value MATLAB will execute the above statement and return the following result − x = 3 It creates a 1-by

command prompt. MATLAB is an interpreted environment. In other words, you give a command and MATLAB executes it right away. Hands on Practice Type a valid expression, for example, Live Demo 5 + 5 And press ENTER When you click the Execute button, or type Ctrl+E, MATLAB executes it immedia

Local Environment Setup Setting up MATLAB environment is a matter of few clicks. The installer can be downloaded from here. MathWorks provides the licensed product, a trial version and a student version as well. You need to log into the site and wait a little for their approval. After downloadi

MATLAB (matrix laboratory) is a fourth-generation high-level programming language and interactive environment for numerical computation, visualization and programming. It allows matrix manipulations; plotting of functions and data; implementation of algorithms; creation of user interfaces; int
