MATLAB Examples

These Matlab examples thoroughly introduce the basics you need to get started. They supplement very well the Tutorial Section.

Basic Matlab Code
Here you can find examples on different types of arithmetic, exponential, trigonometry and complex number operations handled easily with Matlab code...


Example: Simple Vector Algebra
On this page we expose how simple it is to work with vector algebra, within Matlab...

Example: MATLAB Plots
In this group of examples, we create several cosine MATLAB plots, work with different resolution and plot parameters...

Example: MATLAB programming (Script Files)
In this example, we program the plotting of two concentric circles and mark the center point with a black square. We use polar coordinates in this case (for a variation)...

Example: A custom-made Matlab function
Even though Matlab has plenty of useful functions, in this example we develop a custom-made Matlab function. We have one input value and two output values to transform a given number in both Celsius and Farenheit degrees...

Ex.: Matrix manipulation
In this section we study and experiment with matrix manipulation and boolean algebra. This tutorial creates some simple matrices and then combines them to form new ones of higher dimensions. We also extract data from certain rows or columns to form matrices of lower dimensions...

Ex. Dot Product
The dot product is a scalar number and so it is also known as the scalar or inner product. In a real vector space, the scalar product between two vectors...

Ex.: Cross Product
In this example, we are going to write a function to find the cross product of two given vectors u and v. If u = [u1 u2 u3] and v = [v1 v2 v3]...

Complex Numbers
The unit of imaginary numbers is root of -1 and is generally designated by the letter i (or j). Many laws which are true for real numbers are true for imaginary numbers as well. Thus, in this Matlab example...

Future Value of investment
This program is an example of a financial application in Matlab. It calculates the future value of an investment when interest is a factor. It is necessary to provide the amount of the initial investment...

Recursion
Recursion is a kind of tricky and smart construction which allows a function to call itself. The Matlab programming language supports it...

Electricity Cost Calculation
We’ll now implement a kind of electricity cost calculator with Matlab... This calculator will help you estimate the cost of operating any given electrical device or appliance at home, based on the average kilowatt-hours (KWH) used...

Palindromes - working with indices and ascii
A palindrome is a phrase, word, number or other sequence of characters that can be read the same way in either direction...
