Usage of axis function in Matlab: 1. axis([xmin xmax ymin ymax]): This statement sets the range of the x-axis to xmin to xmax, and sets the range of the y-axis to ymin to ymax; 2. axis('equal'): This statement sets the ratio of the x-axis and the y-axis to be equal so that the shape drawn on the graph will not be stretched or compressed; 3. axis('off'): This statement turns off the coordinate axis ;4. axis('tight') and so on.
#In Matlab, the axis function is used to control the range and scale of the coordinate axis. Its usage is as follows:
1. axis([xmin xmax ymin ymax]): This statement sets the range of the x-axis to xmin to xmax, and sets the range of the y-axis to ymin to ymax.
Example:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y); axis([0 2*pi -1 1]);
2. axis('equal'): This statement sets the scale of the x-axis and the y-axis to be equal so that the shape drawn on the graph will not be stretched. or compression.
Example:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y); axis('equal');
3. axis('off'): This statement turns off the coordinate axis.
Example:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y); axis('off');
4, axis('tight'): This statement sets the range of the coordinate axis to be equal to the minimum and maximum values of the plotted data, but it will not automatically Adjust the proportions.
Example:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y); axis('tight');
