How do you create a plot with a grid in MATLAB?

To create a plot with a grid in MATLAB, the most effective method is to use the grid on command immediately after the plot function. By issuing the grid on command, you enable the grid lines on the current plot, which enhances readability and allows you to better visualize the data points in relation to the axes.

When you plot your data first and then call grid on, MATLAB applies the grid overlay to the already created plot, ensuring that the grid lines align perfectly with the coordinates of your data. This sequential approach also allows for modifying the properties of the plot before adding the grid, which can be useful for achieving the desired appearance of the graph.

Other options may not function correctly or may not reflect standard MATLAB practices. For instance, using a grid() command in the plot function is not valid syntax and would not execute as intended. Plotting before the grid command is essential; calling grid before any plotting occurs would have no effect since there would be no existing plot to modify. Lastly, the addGrid() function would not be a recognized or built-in function in MATLAB for adding grid lines, as the proper command is simply grid followed by on or off.
