ECMA is too arrogant. This article attempts to use a simple test example to illustrate the problem.
The prototype of any function is automatically created immediately after it is created:JS Code
Function CoO (){};
Alert (COO. Prototype. constructor); // => function CoO (){}
Prototype of the instantiated coo is pla
I have said "normally ".
A virtual table is generally a pointer of an "array Pointer" (which is roughly the same without careful consideration). That is, an address is saved in the object and then directed to a table (array. We can do this experiment: Write a class with both virtual tables and member data:Code:
Struct coo
{
Int D; // put D at the beginning, but in fact there is a vtable in front of it
Coo
}
Syntax: typestruct{}
The code above defines a struct named coordinate, which contains two float32 of variable x, y, which can be used to represent a planar coordinate.
Add Object method
Other classic object-oriented languages such as java,c#, which define object methods, are included in the definition of class, such as
publicclasscoordinate{
Publicfloatx{get;set;}
Publicfloaty{get;set;}
Print coordinates
Publicvoidgetcoordinate () {
Console.WriteLine ("(" +this. X+ "," +this. y+ ")

member.Determining the size of a class is usually used in rules (2) and (3).Example 1: Basic analysis class Coo { char C; short S; int I; short S2;}; First, the offset of C is 0, and 0 is an integer multiple of 1, so it is not padded; s is offset by 1, and 1 is not an integer multiple of 2, so it is filled with 1;The offset of I is 4, and 4 is an integer multiple of 4, so no padding is necessary; The offset of the S2 is 8, and 8 i
In order to save storage space and speed up parallel program processing, it is necessary to compress the sparse matrix, and the principle of compressing storage is that the same element is not stored repeatedly; 0 value elements are not stored. The storage formats of several commonly used matrices are as follows: COO,CSR,DIA,ELL,HYB, etc. in general, sparse matrices refer to matrices where the element is mostly 0 (some data defines a matrix that is no

operations such as sparse matrices. It supports both dense and sparse data formats.
Is some function calls of the library, from which you can have a general understanding of its functions. CuSPARSE distinguishes functions by level. All level 1 functions only operate on dense and sparse vectors. All level2 functions operate on sparse matrices and dense vectors. All level3 functions operate on sparse and dense matrices.
CuSPARSE Data Storage Formats
The dense matrix indicates that most of the val
matrix.In the experimental process, four sparse matrix formats were used: COO, CSR, ell and HYB. The COO is the most primitive form of sparse matrix storage, using three arrays to record the row, column, and numeric values of each element, which is simple, but not optimal in space. A CSR is a more commonly used format and uses three arrays, each of which is the value of each element and its corresponding c
