The number of knowledge points of a matrix is sufficient to write a linear algebra.In C + +, we encapsulate the matrix into classes:List of programs:(List of patches here)Group parsing:Member Resolution: Matrix-matrix Generation:

Sometimes you need to get the value of the background variable in JavaScript to determine the JavaScript execution logic, or you need to call the C # backend method to get the data , we can use expression is easily implemented, and mainly binds

I learned today.30 page ~49 page.1. The choice of arithmetic type, generally only use int,double. exceeding int is a long long instead of a long. Floating-point type with double instead of float, the cost difference between the two is small.2.

In C #, we can see three types of forced-type conversions, such as casting to signed 32-bit integers, and you can find the following three ways:① (int) () ②convert.toint32 () ③int. Parse ()Three kinds of transformations can be common in some data,
