matlab axis

In MATLAB, the axis command is used to set or modify the limits of the current axes. The syntax of the axis command is:

axis([xmin xmax ymin ymax])

where xmin, xmax, ymin, and ymax are the minimum and maximum values of the x and y axes, respectively.

The axis command can also be used with additional arguments to control the scaling and appearance of the axes, such as:

- 'equal' : sets the x and y axis limits to be the same, creating a square aspect ratio
- 'tight' : sets the axis limits to fit the data within the plot
- 'off' : removes the axis lines and labels from the plot
- 'image' : sets the axis limits to the size of the image data in the plot
- 'square' : sets the aspect ratio of the plot to be a square, regardless of the data range

For example, to set the x-axis limits to range from 0 to 10 and the y-axis limits to range from -5 to 5, the command would be:

axis([0 10 -5 5])
