What is MATLAB and what are its benefits




MATLAB is a powerful software for mathematical computing, data analysis, visualization, and programming. It is used by engineers, scientists, researchers, students, and educators worldwide to solve complex problems in various domains such as engineering, science, finance, biotechnology, and more. MATLAB has many benefits, such as:


  • It provides a user-friendly interface that allows you to work interactively with your data and code.



  • It supports a wide range of data types, formats, and sources, including matrices, arrays, tables, images, audio, video, text, files, databases, web services, and more.



  • It offers hundreds of built-in functions and toolboxes for performing various tasks such as linear algebra, optimization, statistics, machine learning, signal processing, image processing, computer vision, control systems, simulation, and more.



  • It enables you to create custom functions and scripts using the MATLAB language, which is a high-level and expressive language that supports vectorization and matrix operations.



  • It allows you to create graphical user interfaces (GUIs), apps, reports, presentations, and web pages using MATLAB graphics and app building tools.



  • It supports parallel computing and GPU acceleration to speed up your computations and simulations.



  • It integrates with other languages and platforms such as Python, C/C++, Java, .NET, Excel, Simulink, hardware devices, cloud services, and more.



What is new in MATLAB 2021b




MATLAB 2021b is the latest release of MATLAB that offers hundreds of new and updated features and functions. Some of the highlights of MATLAB 2021b are:


  • Code refactoring and block editing: You can now easily improve the readability and maintainability of your code by applying code refactoring suggestions such as renaming variables or functions, extracting subfunctions or scripts, or converting loops to array operations. You can also edit multiple lines of code at once using block editing mode.



  • Python integration: You can now run Python commands and scripts from MATLAB using the py command or the Python Command Window. You can also access Python variables in the MATLAB workspace using the pyenv function.



  • RF PCB Toolbox and Signal Integrity Toolbox: These are two new products that enable you to design, analyze, and visualize high-speed and RF multi-layer printed circuit boards (PCBs) and high-speed serial and parallel links. You can use these toolboxes to model components with parameterized or arbitrary geometry; perform electromagnetic analysis using frequency-domain method of moments and other techniques; simulate standard-compliant IBIS-AMI models for equalization and clock recovery; generate experiments covering multiple parameters; extract design metrics; and visualize waveforms and results.

How to use MATLAB 2021b features




Now that you have installed and activated MATLAB 2021b for free with crack, you can start using its features and functions. Here are some examples of how to use some of the new features in MATLAB 2021b:


Code refactoring and block editing




To improve your code quality and readability, you can use code refactoring suggestions that appear as light bulbs in the MATLAB Editor. For example, you can rename variables or functions, extract subfunctions or scripts, or convert loops to array operations. To apply a code refactoring suggestion, simply click on the light bulb icon and select an option from the menu.


To edit multiple lines of code at once, you can use block editing mode. To enter block editing mode, press Ctrl+Alt+Shift+Down Arrow or Ctrl+Alt+Shift+Up Arrow. You can then select a rectangular region of code and edit it as a single block. To exit block editing mode, press Esc or click anywhere outside the block. You can also use the Edit menu or the context menu to access block editing commands.


Python integration




To run Python commands and scripts from MATLAB, you can use the py command or the Python Command Window. The py command allows you to execute Python expressions or call Python functions from MATLAB. For example, you can type py.print('Hello, world!') in the MATLAB Command Window to print a message using Python. The Python Command Window allows you to enter and execute Python commands interactively in a separate window. To open the Python Command Window, go to the Home tab and click Python in the Environment section.


To access Python variables in the MATLAB workspace, you can use the pyenv function. The pyenv function allows you to get or set the current Python environment, which includes the Python version, executable, library, and path. For example, you can type pyenv in the MATLAB Command Window to see the current Python environment settings. You can also type pyenv('Version','3.9') to switch to a different Python version.


RF PCB Toolbox and Signal Integrity Toolbox




To design, analyze, and visualize high-speed and RF multi-layer printed circuit boards (PCBs) and high-speed serial and parallel links, you can use the RF PCB Toolbox and Signal Integrity Toolbox. These are two new products that are available as add-ons for MATLAB 2021b. To install these toolboxes, go to the Add-On Explorer in MATLAB and search for RF PCB Toolbox or Signal Integrity Toolbox.


The RF PCB Toolbox allows you to model components with parameterized or arbitrary geometry; perform electromagnetic analysis using frequency-domain method of moments and other techniques; simulate standard-compliant IBIS-AMI models for equalization and clock recovery; generate experiments covering multiple parameters; extract design metrics; and visualize waveforms and results. You can use the RF PCB Designer app or the command-line interface to access these features.


The Signal Integrity Toolbox allows you to model high-speed serial and parallel links using S-parameters, IBIS models, or SPICE netlists; perform signal integrity analysis such as eye diagram, bathtub curve, jitter, BER, and crosstalk; optimize link performance using equalization techniques such as continuous-time linear equalizer (CTLE), decision feedback equalizer (DFE), or feed-forward equalizer (FFE); and generate test signals and reports. You can use the Signal Integrity Analyzer app or the command-line interface to access these features.
