bạn có thể muốn mô hình kinh doanh của bạn. Không phải mọi dự án đòi hỏi mô hình kinh doanh. Tuy nhiên, có những tình huống nhiều mô hình kinh doanh bổ sung thêm rất nhiều giá trị. Chúng tôi sẽ thảo luận về một số những tình huống này. Sau đó chúng tôi sẽ nhận được vào các yếu tố cụ thể trong mô hình kinh doanh. | T- 56 MATLAB Demystified Figure 3-6 A labeled plot generated with the fplot command For the current example we replaced f exp -t sin t with y exp x . sin 10 x 5 . The difference is that in the second case we used matrix multiplication indicated by typing . . Well we are back to the old plot x y command. What are some other ways we can spruce up your basic two-dimensional plot One way is to add a grid to the plot. This is done by adding the phrase grid on to your plot statement. For the next example we will plot y tanh x over the range -6 x 6 with a grid display. First we define our interval x -6 6 Next we define the function y tanh x The plot command looks like this and produces the plot shown in Figure 3-7. Plot x y grid on CHAPTER 3 Plotting and Graphics Figure 3-7 A plot made with the grid on command The Axis Commands MATLAB allows you to adjust the axes used in two-dimensional plots in the following way. If we add axis square to the line containing the plot command this will cause MATLAB to generate a square plot. If we type axis equal then MATLAB will generate a plot that has the same scale factors and tick spacing on both axes. Let s return to the example y tanh x which we plotted in Figure 3-7. If you run this plot with axis square you will get the same plot that we did using the default settings. But suppose that we typed plot x y grid on axis equal In this case we get the plot shown in Figure 3-8. Notice that the spacing used for the y axis in Figure 3-7 and Figure 3-8 are quite different. In the first case the spacing used on the vertical or y axis is different than the spacing used on the x axis. In contrast in Figure 3-8 the spacing is identical. T- 58 MATLAB Demystified Figure 3-8 Plotting y tanh x using the axis equal option As you can see from this dramatic example we can use the axis command to generate plots that differ quite a bit in appearance. Hence we can use the command to play with different plot styles and select what we need for .
