Today, we are going to build a DIY metal detector with the help of these devices which will help make the process easy and fun. The end product, the metal detector itself once built can help you find metallic stuff under the ground, who knows what might just be buried there waiting for you! Here are the …
Solving a system of equations with two unknowns is a very easy cake to bite but when the number of unknown exceed two, solving the system of equations becomes complicated and time-consuming. In this post, we are going to show you how you can use your computer and Matlab to solve a system of many …
Lately we have learned some basics about Matlab matrix operations. Here come the part 2 of that post, where we will test our abilities of manipulating matrices in Matlab Matlab matrix operation exercise Exercise 1 Create a 1 x 5 vector A with all elements equal to 0 Exercise 2 Create a 3 x 1 …
We have so far been working with numbers, totally ignoring one of the most rewarding ability Matlab put to our use: the possibility to work with symbolic expressions. In many college algebraic courses, it is taught how to use and simplify equations with symbolic expressions, where one of the major task is to be learn …
It’s a great time to hit the road running. We have got enough Matlab lessons to start handing you some nice Matlab challenges to help you to assess yourself. Here are some Matlab exercises. Contents: Matlab Exercise 1 Matlab Exercise 2 Matlab Exercise 3 Matlab Exercise 4 Matlab Exercise 5 Matlab Exercise 6 Matlab Exercise …
Sorting Matrices in Matlab is one of the easiest things to do when you happen to know the language to use to order the software to do so. In this example, we will deal with vectors, and we will write simple programs sorting a vector in the ascending and descending order all for the objective …
The Euler method is a numerical method that allows solving differential equations (ordinary differential equations). It is an easy method to use when you have a hard time solving a differential equation and are interested in approximating the behavior of the equation in a certain range. Here we will see how you can use the …
We worked on creating a decibel meter using the Arduino board here and how to assemble an audio level indicator. This one is a simple and perfect electronic project for beginners. Let’s put this voice control LED board together so the LEDs blink every time noise is detected. Let’s get started. Here are the elements contained in …
We have recently learned how to create functions in Matlab and make use of them. Feel free to have a look at it to know how you will fully make use of the following. In this session, we are going to see how we can write few lines of code to ask Matlab to help …
Linear equations are some of the simplest equations and the easiest to plot. These types of equations appear abundantly in most subareas of mathematics and mostly in applied mathematics. Graphing such an equation by plotting points comes down to finding points belonging to the graph using its equation. It is pretty simple to find the …
Working and constructing for loops in Matlab happen the exact same way they do in other programming languages, at the only difference that in Matlab the first index the for loop goes through is never zero. In Matlab, the first index is 1, and this is information you should always remember while working with for …
We have recently used the EZPLOT technique to plot in Matlab, which is indeed an easier technique to plot compared to the one we are going to make use of in this post. Plotting functions gives us a visual description of the behavior of the latter as we change the system variable. And Matlab is …
I will define a vector here as being a matrix with either a single column and many rows or a single row and many columns.The following are two vectors Now that we are settled on what a vector is, let’s look how to manipulate vectors using Matlab. Vectors in Matlab Create a vector in Matlab …
If you ever tried to work with huge matrices, you will know how unpleasant and tedious. Here is where Matlab come to play, it makes working with Matrices easier. With Matlab, one of the major problem for beginners is to understand how the software works and what the software need in order to help them …
The aim of this session is to use a basic example to illustrate how to use the Newton Raphson method in Matlab. We will make use of the ode45 solver, and use boundary conditions in the following example. Here come the exercise With boundary conditions Here is the route we will take Newton Raphson method …
