How can you specify the x-axis limits in a MATLAB plot?

The function that allows you to specify the x-axis limits in a MATLAB plot is xlim(). This function is specifically designed to get or set the limits of the x-axis, providing a straightforward way to define a range for your data on the horizontal axis of the plot.

When you use xlim([xmin xmax]), you set the minimum and maximum range of the x-axis, which can help focus on specific areas of your data that are of interest. Adjusting the x-axis limits can also improve the visualization of trends or patterns that might otherwise be lost in a more extensive range.

In contrast, the other options do not accomplish this specific task. limitx() and axisLimits() are not built-in MATLAB functions for setting axis limits, which means they would generate an error if used. Meanwhile, ylim() is used to set the y-axis limits, further distinguishing its purpose from that of xlim(). This clear distinction between the functions reinforces the importance of using the correct commands for effective data visualization in MATLAB.
