How does MATLAB mark the coordinates of the upper and right sides?

In matlab, the coordinate axes are displayed on the left and bottom by default. In order to move the coordinate axis, you can use the setting function to set the coordinate axis position.

The specific statement is

set(gca，' xaxislocation '，' top ')；

set(gca，' yaxislocation '，' right ')；

Where gca represents the current image. Xaxislocation and yaxislocation represent the x-axis and y-axis respectively, and the upper right represents the direction respectively.

MATLAB[ 1]？ It is a commercial mathematics software produced by MathWorks Company in the United States. It is an advanced technical computing language and interactive environment, which is used for algorithm development, data visualization, data analysis and numerical calculation. Mainly includes MATLAB and Simulink.

MATLAB is matrix &；; The combination of the word laboratory means matrix laboratory. It is a high-tech computing environment released by mathworks Company in the United States, which is mainly oriented to scientific computing, visualization and interactive programming. It integrates many powerful functions such as numerical analysis, matrix calculation, scientific data visualization, modeling and simulation of nonlinear dynamic systems in an easy-to-use window environment, and provides comprehensive solutions for scientific research, engineering design and many scientific fields that need effective numerical calculation, and to a great extent gets rid of the editing mode of traditional non-interactive programming languages (such as C and Fortran), which represents the advanced level of international scientific computing software.

MATLAB, Mathematica and Maple are also called the three major mathematical softwares. It is second to none in numerical calculation in mathematical science and technology application software. MATLAB can perform matrix operations, draw functions and data, realize algorithms, create user interfaces, and connect programs in other programming languages. Mainly used in engineering calculation, control design, signal processing and communication, image processing, signal detection, financial modeling design and analysis and other fields.

The basic data unit of MATLAB is matrix, and its instruction expression is very similar to that commonly used in mathematics and engineering. Therefore, it is much simpler to solve problems with MATLAB than to do the same thing with C, FORTRAN and other languages, and MATLAB also absorbs the advantages of Maple and other software, making MATLAB a powerful mathematical software. Support for C, FORTRAN, C++ and JAVA has also been added in the new version.
