For example, if you issue the command plot (x,y,'k*-'),MATLAB will plot the

curve using a black solid line with an *marker shown at each data point. If you do not spec-

ify a line color, MATLAB automatically assigns a color to the plot.

Using the title('text')command, you can add text on top of the plot. The

xlabel('text')command creates the title for the x-axis. The text that you enclose

between single quotation marks will be shown below the x-axis. Similarly, the ylabel

('text')command creates the title for the y-axis. To turn on the grid lines, type the

command grid on(or just grid). The command grid offremoves the grid

lines. To turn on the minor grid lines, as shown in Figure 15.13, type the command grid

minor.
