Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to tell you guys that how to design a simple algorithm for Stepper Motor Speed Control in MATLAB by simply sending different commands to the serial port from Matlab to Arduino. You should first read Stepper Motor Speed Control using Arduino because I am gonna take that tutorial further and will do the Stepper Motor Speed Control in Matlab. So, I would suggest you to first have a look at that tutorial before reading this one. Moreover, you should also have a look at DC Motor Direction Control in Matlab, DC Motor Speed Control using Arduino. Stepper Motor Direction Control Direction Control in Matlab, Stepper Motor Direction Control using NI LabVIEW and Stepper ...
Hey learners! Welcome to another exciting lecture in this series of signals and systems. We are learning about the transform in signals and systems, and in the previous lectures, we have seen a bulk of information about the Laplace transform. If you know the previous concepts of signal and system, then this lecture will be super easy for you to learn, but if your concepts are not clear, do not worry because we will revise all the basic information from scratch for our new readers. So, without wasting time, have a look at the topics of today.
What is z transform?
What is the region of convergence of z transform?
What are some of the important properties of the region of convergence?
How to solve the z transform?
What is an example of the z transform in MATLAB?
What are the methods fo ...
Hey peeps, welcome to The Engineering Projects. We are talking about matrices, and if you want to learn them from scratch, you must go to the introduction to matrices in MATLAB. Today, we are learning how to perform different arithmetic operations on matrices. You will also see some interesting commands that are only applicable to the matrices. Here, it is important to notice that in MATLAB, the matrices are performed in the command window and there is no need to have the programming skills to perform them. Even if you are new to programming, you can easily perform the operations in MATLAB. We’ll discuss different basic operations on the matrices and will also perform each of them in MATLAB. Most of them are urinary operations and some of them are binary. Here is a small glimpse of today’s ...
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 learners, Welcome to another tutorial on MATLAB. In the previous tutorial, we learned a lot about MATLAB's command window, saw some exciting commands related to the system, and found guidance from the pre-defined data. In this lecture, you will learn a great deal about the other two types of windows we defined in the earlier sessions. Let me discuss the points that will be discussed today.
What is a Figure window?
How to get started with the figure window?
How can you change the background colour of the figure window?
What are some functions of the figure window?
Give a brief introduction to the editor window.
What is the live script?
How to run code on the live script?
What is the difference between the run all and run section options in MATLAB?
We shall discuss all ...

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 ...
Hello! Welcome to the engineering projects. This is the second part of the signal and system series in which we will discuss some essential classifications of simple signals. In the previous session, we discussed the introduction of signals and systems and also ran some simple codes on MATLAB for the implementation of some simple codes.
In this session, we are discussing some essential types of signals, and the best part is that we will implement all the signals in MATLAB for the best understanding. Here is a quick glance at all the topics that we will discuss today:
Continuous-Time Signals
Discrete-Time Signals
Periodic Signals
Aperiodic Signals
Even Signals
Odd Signals
Deterministic Signals
Non-Deterministic Signals
Energy Signals
Power Signals
What are functions?
Some ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a simple tutorial on Image zooming with bilinear Interpolation in MATLAB. We have seen many software in which there's an option of zooming an image. For example, if you have used paint or photoshop then you have seen that you can zoom your image quite easily by clicking a button. Today's we are gonna do the same thing but in MATLAB and we will have a look at the code behind this feature.
Now, when we are zooming some image then in fact we are increasing the pixels of that image and in order to do that we have to fill those extra pixels with the color of their neighbor pixel. This thing is know as interpolation. There are many different techniques for in ...
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. 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 ...
