MATLAB R2020a software introduction
Compared with the previous MATLAB2019b version, the new MATLAB2020a has many new enhanced functions, such as shared work, App Construction, data import and analysis, data visualization, big data, language and programming have all been improved and optimized in many ways, aiming to bring users a new user experience. In addition, the software has also added many new functions, coordinates, chart containers and other functions. The new built-in coordinate axis interaction allows users to browse data through panning, zooming, data prompts and three-dimensional rotation by default. , allowing you to have better browsing results.
MATLAB R2020a function introduction
1. Desktop basics: enter statements on the command line and view the results.
2. Matrices and arrays: Mainly processing arrays and matrices, which can be processed in whole or in part. A matrix refers to a two-dimensional array commonly used to perform linear algebra operations.
3. Array index: Variables are usually arrays that can contain many numbers. If you want to access selected elements of an array, use indexing.
4. Workspace variables: The workspace contains variables that are created in the software or imported from data files or other programs.
5. Text and characters: Create a string array for text, or a character array for data.
6. Call functions: Provides a large number of functions for performing computing tasks. To call a function, enclose its input parameters in parentheses.
7. Two-dimensional and three-dimensional graphs: Graphical functions include two-dimensional and three-dimensional drawing functions, which are used to present data and communication results in a visual form.
