Hello, readers welcome to the new post. In this post, we will learn What is MATLAB? The MathWorks company creates the high-level programming language MATLAB. It is the basic default language used for solving high-performance computing for research and computing services. The main objective of MATLAB is to help difficult numerical problems such as aerodynamics, fluid dynamics, climatology, and meteorology in simple form and faster.
Matlab Language was developed by Gerald W. Joseph, Walter Ren Miguel Nicolelis, , Félix Sadurní, and Edward Teller to come up with features of high-level languages and matrix algebra.
Introduction to Matlab
- MATLAB’s full form is Matrix Laboratory. That is a high-performance language that is used for technical problems. It was first time used in 1984 and made by Cleve Molar of the company MathWorks.Inc.
- MATLAB is written in C, C++, and Java. In this language matrices are made, different functions are plotted, algorithms are used and user interfaces are made
- It is known as a programming language and platform for programming. It helps to compute statements in a common window.
Command Window:
- Here we write and execute statements since it need high-speed prototyping. These statements are not saved. It used for small and easy-to-execute programs.
Editor (Script)
- This window helps to apply larger programs that has many statements and complicated functions. They saved in file extension ‘.m ‘
Workspace:
- This window variable values that are made in the editor are shown
Command History window :
- In this window log of statements that worked in the present and previous sessions of Matlab is shown. The Command history defines time and date of every session for short date types of operating system with statements from that session.

Basic Operators
- The primitive matrix comes with 1 by 1 and defines that 1×1 that shows that (2.0*10-5)+5 The data x and y in the matrix X = (1,1) and y = (0,0).
- It is good to use for pictures in the array so each pixel of the array denotes the pixel of the picture (x and y).
- For Programming C language product of two matrices is a multiple of two matrices in MATLAB is easy and fast. In matrix multiplication, xm=X * X and ym=Y * Y.
Functions
- Stds First things first, here we will make a matrix by using matplotlib functions
- Matlab and look at the documentation. main() -> pb.run() Ended Therefore, it’s now time to run the code.
- For that, we need to change the code from above into: To run it on your local machine, simply execute it with C:\MyCode\main>./cocoa run m1.m1.m2.m3.m4.m5.m6.m7.m8
Pros and cons of MATLAB
Pros
- MATLAB helps to make 2 and 3-dimensional graphics.
- It can easily be used by beginners and has features to learn easily as a new programming language.
- It has algorithm development higher speed than other programming languages.
- It comes with different tools and has certain libraries for code creation and making outputs.
- It has interfacing with other languages such as Python, C#, Java, and C++.
Cons
- In this software, different functions are not made in a single file so we must make separate files for each function
- Different commands in MATLAB are compatible with MATLAB, so programming features for languages are not easy to translate.
- This software is not easy to use freely for MATLAB using business or personal use there is a need of MATLAB licensing.
