Hello, learners welcome to The Engineering Projects. We are working on MATLAB, and in this tutorial, you are going to learn a lot about matrices in MATLAB. We are going to learn them from scratch, but we will avoid unnecessary details about the topic. So, without wasting time, have a look at the topics that you will learn in detail.
What is an array?
What is the matrix?
How can we declare a matrix in MATLAB?
What are the different types of matrices?
Can we find the unknown values of two equal matrices?
How can we solve the simultaneous equation in MATLAB?
What is an Array?
In this world of technology, the use of data is everywhere, and therefore, we can say there is a need for arrays in every field. You will find the reason soon. But before this, look at the introduction of a ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about How to Create m File in MATLAB. It is also known as New Script or Editor in the MATLAB. It's an amazing MATLAB tool. We can write the complete source code on editor. If we want to visualize the result of the particular statement we should not put a semicolon after that statement in MATLAB. Before going into the details of this tutorial, you must first have a look at Introduction to MATLAB and if you don't know about MATLAB variables then you must read Declaration of Variables in MATLAB.
By doing this and by pressing the Run (Green Color) button at the top of the editor we will be able to see the result on the command window. In ot ...
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 ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Generating Simple Signal in MATLAB. Signals are of great importance in our daily life. The signals are basically the graphical display of the analog values. We can estimate the severity level by the shape of the signals. The signals have a very wide range of applications in our daily lives. If we observe the shape of the AC voltages of 220V that is supplied in our homes, it is a sinusoidal signal. So, its an application of the signals.
Signals also play a vital role in the medical field. While performing ECG and EEG tests in hospitals, doctors visualize the signals displayed on the screen and they can estimate the severity of the ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to show you Color Detection in MATLAB Live Video. In this project I am gonna take a live video feed from a camera and then will detect a specific color in that video feed. I have posted a project before in which I have done the same Color Detection in Images using MATLAB but that color detection was for images but in today's post I am gonna do the color detection in MATLAB for live video feed.
I have designed this project in MATLAB 2009 and have also tested it on MATLAB 2015 and it works fine. So, I think it will work on any version of MATLAB. You must have the image processing toolbox in your MATLAB. If you got any questions then ask in comments and I will t ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Convert m File into p File in MATLAB. Now the question arises that why we need to do that? & the answer is if you want to protect your code and don't want anyone to access it then you need to your Convert m File into p File. P File is like an encrypted file which performs the same functionality as your original m file but no one can get the code out of it.
Like me explain it with an example, suppose you are some sort of developer and you have created some code for a company and now you want to protect your code and just send the company some sort of software. MATLAB has a function in which you convert your m-file into p-file and no one can open ...
Hello friends, hope you all are fine and enjoying. Today I am going to share a very interesting tutorial which is Analysis of Sinusoidal Pulse Width Modulation of AC signal. I will try to explain this tutorial in parts. I will explain the code step by step and at every step we will see that what are the purpose of commands, which are written in that particular code. Before doing that first of all let me explain what is meant by Pulse Width Modulation.
Pulse Width Modulation or PWM is a technique which is used for getting Analog Results with digital means. We can say that some Digital Control or some Electronics algorithm is used to generate square waves. Square wave is in fact a signal which is generated through switching between ON & OFF stat ...

Hello friends, I hope you are doing great. Today, I am going to share an expert level project which is ECG Averaging in MATLAB. If you are new to ECG then you should have a look at Introduction to ECG. I have already shared ECG Simulation using MATLAB in which we have seen how to simulate an ECG signal and then diagnose heart disease. We have also extracted ECG features in that project. So, if you guys haven't read that tutorial then I would suggest you to not read this one. First read ECG Simulation using MATLAB and then you should read this tutorial. Today's project is quite an extension of our previous project ECG Simulation using MATLAB. Our team has designed this project after quite a lot of effort that's why its not free to ...

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%. ...
Hello friends. In this lecture, we are going to have a look at the different kinds of MATLAB data types.
As we have already seen in previous lectures, MATLAB stands for MATrix LABoratory and allows us to store numbers in the form of matrices.
Elements of a matrix are entered row-wise, and consecutive row elements can be separated by a space or a comma, while the rows themselves are separated by semicolons. The entire matrix is supposed to be inside square brackets.
Note: round brackets are used for input of an argument to a function.
A = [1,2,3; 4,5,6; 7,8,9];
An individual element of a matrix can also be called using ‘indexing’ or ‘subscripting’. For example, A(1,2) refers to the element in the first row and second column.
A larger matrix can al ...
