How to Label a Series of Points on a Plot in MATLAB You can label points on a plot with simple programming to enhance the plot visualization created in MATLAB®. You can also use numerical or text strings to label your points. Using MATLAB, you can define a string of labels, create ...
I am trying to program a function called draw_constellation. By using ginput,the user would click on the figure and a plot point will appear. Any subsequent plot points would be connected with a line. My problem is connecting the third point with the second point and so on. Currently...
Use the meshgrid function to find all points in the plane, then associate the points with the z-axis, and then use the surf function to draw a curved surface. (2) 指定颜色(Specify the color) 若不指定曲面图的颜色,则曲面图的颜色会随着z轴的数值增大而变色。
The beauty of data is not limited to the straight line world. The polar graph depicts the periodicity and symmetry of data from its unique perspective. The polar function or polarplot function in Matlab can distribute data points in the polar coordinate system, like blooming flowers, showing the...
You can also use it to manipulate and plot the data returned by these functions. You can use the object to fill the points interactively in situations where you might want to mix a non-BRISK interest point detector with a BRISK descriptor....
