1. How do I ask an area of any polygon?
Provides a good function in Matlab
Polyarea (X, Y) can find the area of the polygon around any closed curve determined by (x, y). Of course, the shape of the curve can be obtained from the (x, y) two-dimensional interpolation and then the dual integration can also be calculated.
2. How to implement an idea of any curve on the screen and return to the coordinate of this curve?
The rectangle is generally used to simulate this process. Get a function of the rectangular box is
GetRect ();
For example, Figh = get (0, 'currentfigure');
Rect = getRect (Fig ";
Rectangl = Rectangle ('Position', RECT);
SET (Rectangl, 'EdgeColor', [1 1 1]) can achieve this process
3. When I debug VC program today, I found this problem.
If you introduce a third-party lib library in the program, pay attention to if the person providing the library does not set Generate Debug Info when compiling the lib file, you have this setting, so when compiling A vc60.pdb missing debug info will occur, this is hard to find, so the two parties have consistently set!
