Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about how to convolve the signals using an amazing software tool, MATLAB. MATLAB is an efficient tool for signal processing. MATLAB basically works on matrices. First of all I would like to tell you a bit about the convolution. In engineering terms, convolution describes the output of the Linear Time Invariant (LTI) systems.
Convolution is basically an integral which tells us about the overlapping of one function as it is shifted over another function. Convolution and cross correlation are similar. It has a wide range of applications e.g. computer vision, probability, statistics, engineering, differential equations, signal processing etc. ...
Hello friends! I hope you will be absolutely fine and having fun. Today, I am going to share that how to make a program for Stepper Motor Direction Control using Matlab. I am going to share this tutorial on demand. I have also make different programs for DC Motor Direction Control using Arduino, DC Motor Direction Control in Matlab, DC Motor Direction Control using LabVIEW, DC Motor Speed Control using Arduino, DC Motor Speed Control using Matlab and Stepper Motor Direction using Arduino in my previous tutorials. So before going into the detail of this tutorial you must have to go through these tutorial because I will use the same hardware and a bit changed Arduino source code. In this tutorial I will make an algorithm to send different commands ...
Hello friends, hope you all are fine and having fun with your lives. In today's post we are gonna see How to detect Circles in Images using MATLAB. It's quite a simple and basic tutorial but quite helpful as today I was working on a project in which I need to do so but all the codes available online were for detection and tracking of circles in live images. So, I thought to share this one on our site. I have also posted another tutorial Color Detection in Images using MATLAB, so I think its better if you check that one as well.
We all know about MATLAB, which is a great tool for image processing and quite easy as it has a strong Help section. I haven't posted much tutorials on MATLAB in my blog so from now on I am gonna post tutorial on MATLAB as ...
Hey, pupils welcome to the next session about the Fourier transform. Till now, we have learned about the basics of Fourier transform. It is always better to understand all the properties of a mathematical tool to understand its workings and characteristics. You will observe that most of its properties are similar to the topics that we have discussed before, and the reason is, that all of them are transforms, and the core objective of these transforms is the same. We have learned about the simple and easy discussion of the Fourier Transform, but when dealing with complex problems, it involves the usage of different properties so that we do not have to repeat the calculations all the time to get the required results. Have a look at what you are going to learn today:
What are the basic prope ...
Hello learners. Welcome to The Engineering Projects. We all know that matrices have been used in the engineering field for a long time, and they have a vital role in the calculation of different data. Therefore, we are learning about some very special kinds of matrices that are usually introduced to engineers at a higher level. Till now, we have seen some general operations on matrices and also examined the special kinds of matrices. Yet, today, we are moving a step forward and learning about some complex types of matrices that require strong basic concepts. So, have a glimpse at the topics that you are going to learn, and then, we’ll start practicing.
What is a matrix?
What are the different types of matrices that are less common?
How can we implement some interesting commands in MAT ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a project named as DTMF Decoder using MATLAB. In this project, I have designed a keypad in MATLAB using the GUI functionality of MATLAB. After designing the keypad, I have assigned a tune to each of these buttons. Obviously the tune attached to each button is different and when we press any of these buttons, then the MATLAB recognizes the respective button.
This project is designed in MATLAB and I have tested it on MATLAB 2009 and MATLAB 2014 and it works fine on both of them. Code is given below in this tutorial for download. f you got problem in it then ask in comments and I will try to resolve them. So, let's get started with DTMF decoder in MATLAB.

Hello everyone! I hope you all will be absolutely fine and having fun. In this tutorial, I am going to give you a detailed Introduction to MATLAB. I will explain in detail, step by step procedure of using MATLAB for the first time. First of all, I would like to tell you a bit about the MATLAB software. MATLAB basically works on matrices and it is an excellent software for different kinds of simulation based projects as well as hardware based projects and specially, it is good for the Engineering Projects.
MATLAB can be used for the manipulation purpose in order to obtain the proper results. It is very easy to use this software and most of the students prefer to use this software for their projects. So, this shows that MATLAB is a user friendly s ...
Hello Pupils, We are learning about signals and systems, and till now we have learned some basic information regarding signals, but we know a little about systems till now. We have learned about the system in our previous lectures. To have a clear concept, we have arranged this tutorial in which we are studying the systems and their classification. Have a quick glance at today’s topics:
What is a system?
What are the various types of systems?
What is the principle of homogeneity?
What is the principle of superposition?
How can we compare each type while keeping their differences in mind?
To keep things simple, we’ll also have examples of some of these signals. Yet, the first thing that we are going to do is to revise the basic definition of the system so that we may move forward. ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about How to use MATLAB. This is an on demand tutorial. The tutorial will help you to learn the the basics of the MATLAB and will elaborate the use of the different tools of it e.g. command window, m.file, Graphical User Interface (GUI) and simulink. Before into the details of this tutorial you must go through Introduction to MATLAB first for the better understanding of this tutorial. Each of the tools has its own importance while making an algorithm in MATLAB. Command window basically deals with the shorter commands where there is a need of quick execution. Command window shows the result of all of the executed commands if there is no s ...

This post is the next part of our previous post Financial Calculations in MATLAB named as Implementation of Black Litterman Approach in MATLAB, so if you haven't read that then you can't understand what's going on here so, its better that you should first have a look at that post. Moreover, as this code is designed after a lot of our team effort so its not free but we have placed a very small cost of $20. So you can buy it easily by clicking on the above button.In the previous post, we have covered five steps in which we first get the financial stock data, then converted it to common currency and after that we calculated the expected returns and covariance matrix and then plot the frontiers with and without risk free rate of 3%. ...
