Second, use meshgrid Command to generate horizontal and vertical cross grid coordinates, The specific command is as follows ：įinally, generate vertical coordinates and draw. įirst, take the horizontal and vertical coordinates, Enter the following command Peaks It is called multimodal function, Commonly used for the demonstration of 3D surfaces. The difference is, The former draws a surface approximated by a mesh, The latter draws a true surface. The commands for drawing 3D surfaces are mesh(x,y,z) or surf(x,y,z). Stay MATLAB Draw three-dimensional arrow function inĮnter the following commands in the command window, The figure shown in the figure can be obtained.

Stay MATLAB The command for drawing 3D curves in isĪmong x,y,z They are the horizontal of points 、 Vertical and vertical coordinates ,S For the string, matlab Four dimensional graph Similar to the drawing string of two-dimensional graphics.

With vectors y=(1,2,5,4.5,3,6,1) The components of are ordinates, The component serial number is the abscissa drawing sequence connecting line. Y Sometimes it can be a matrix, At that time, multiple curves will be drawn for the same independent variable. In the command window help plot Commands can be viewed S Specific writing method of. Matlab Implicit function drawing by entering. The specific graphic drawing command is ：Īmong X,Y It's a vector, They are vectors composed of abscissa and ordinate of all points ,S It's a string, Used to determine the color of the line, The drawing shape of points and the link mode between points.

īecause MATLAB The figure is drawn by tracing points 、 Connected to achieve, Therefore, when drawing simple plane graphics, it is necessary to provide the horizontal and vertical coordinates of a series of points on the graphics, Then link these points. Īt the same time, it supports drawing multiple graphics on the same picture, In order to distinguish different graphics, Available in different colors 、 size 、 Shape and link mode to distinguish different graphics. The graphic drawing is realized by providing the point coordinates of key positions and the specific link between points. MATLAB Graphics are usually drawn by tracing points 、 The way of connection.
