Then we open the project and choose to create a new project. For convenience, I created a folder named sil-test on the desktop to store the files of this project.
After you click Save, the following page appears, and you want to add the file.
As a result, I created two new text files in the folder and renamed them with the v suffix (one as the module of OpenGL and the other as test beach ).

With the neural network of small partners know that the data needs to be normalized, but why to do normalization, the problem has always been ambiguous, and there is no more than the answer on the net, the small series spent a period of time, made some research, give us a careful analysis, why do normalization:
1. Numerical problems.
There is no doubt that normalization can indeed avoid some unnecessary numerical problems. The magnitude of the input variable does not cause a numerical problem,

Let me tell you about it.2.2.1 Triangle area with coordinate pointsWe all know the most
There are many online draw algorithms, but it is not easy to achieve high speed and simplicity. Slope-phase multiplication is one of the simplest methods, but it takes a lot of time to calculate each point for multiplication and division operations. The following describes Bresenham's efficient line-drawing algorithm, you only need to add or subtract the coordinates of each vertex.The simplified algorithm is described in the pseudo Pascal Language as follows:Procedure DrawLine (x1, y1,
the relational database model expression. Decision-free data analysis and decision-making data analysis are two main applications of Rough Set Theory in data analysis. Rough set theory provides the knowledge reduction and core methods to analyze redundant attributes in information systems.If the set B belongs to a and has no redundant attributes, the conciseness of B is a or at, which is marked as red (AT). The intersection of the conciseness in at is called the at core, it is recorded as core
Returns the maximum number of steps of multiplication and division. x ^ N can be obtained.
In fact, the answer is a maximum of 13, but because the branches of the tree are extremely large, while iddfs, we need to add two pruning
1 If the maximum value of the current sequence is M * 2 ^ (DEP-k)
2. If there are two numbers greater than N, the Branch is subtracted. Because there is only one useful one, we can get the answer through another shorter path.

You have a quadrilateral shaped land whose opposite fences are of equal length. you have four neighbors whose lands are exactly adjacent to your four fences, that means you have a common fence with all of them. for example if you have a fence of LengthDIn one side, this fence of LengthDIs also the fence of the adjacent neighbor on that side. The adjacent neighbors have no fence in common among themsel
Concept
The determination of the positional relationship between two line segments in a plane is widely used in many fields, such as games, CAD, and graphic processing.AlgorithmAn important part. This article will describe a mainstream and high-performance judgment Algorithm in a popular language as much as possible.

Example 52 plot a curve
This is a curve equation given in the form of parameters. As long as the parameter vectors are given and then the X and Y vectors are obtained respectively, the curve can be output:
> T =-Pi: PI/100: PI;
> X = T. * Cos (3 * t );
> Y = T. * sin (T). * sin (t );
> Plot (x, y)
After the program is executed, open a graphical window and draw the following Curve

Can you paste the image part at any position in the same region, this is to cut the plug, and then we set it to a variable, and use the mouse to customize the size of the paste, it must be combined with the Windows message loop mechanism to use the plug, when mousedown, we get a coordinate of him. When mouseup, we get a
