Label: gradient descent method, cut vector, method Vector Zookeeper First, it indicates that the gradient is perpendicular to the cut vector of the curve, that is, the gradient direction is the direction of the normal vector: Set the curve x = x (t), Y = Y (T), and z = z (T) to the surface u (x, y, z) = a curve on C (

C ++ is based on the vector graphics library cairo graphics, vector graphics cairo // Sudo apt-get install libcairo2-dev // pkg-config -- cflags -- libs cairo //-I/usr/include/cairo-I/usr/include/glib-2.0-I /usr/lib/x86_64-linux-gnu/glib-2.0/include-I/usr/include/pixman-1-I/usr/include/freetype2-I/usr/include/libpng12-lcairo # include Compilation in Ubuntu: G ++ 'pkg-config -- cflags cairo 'test_cairo.cpp

Before doing a bit of something, to fit 6 and plus, do your own cut map to find it really annoying enough.

Today, I have nothing to do with it. I 've been reading about it for a long time on my computer. When I saw 43rd entries, I found that, as mentioned above, the algorithm replaces the manual loop. No doubt arises. I remember the operator [] operation (subscript operation) was the most efficient loop when I read the vector source code ). The algorithm is fast. The following is a test code: // Test class and call Function Class AAA{Public:Void MakeFul

C ++ Study Notes (15th): How the vector object grows in the memory space, learning notes vector How does a vector object increase in memory? We all know that vector objects are dynamically stored.

In practice, the vector series in c ++ -- Some vector exceptions Today, we will write some vector exceptions that can be captured. Out_of_rangeThe array is out of bounds. The vector automatically increases the capacity, but if the index exceeds the current size, an exception is thrown. # Include # Include

As in the title, if I were to answer before, I would say, yes, in the multi-threaded environment to operate the vector, do not need to add synchronized.But I accidentally saw an article today, I found that my previous idea was wrong, the address of this article:http://zhangbq168.blog.163.com/blog/static/2373530520082332459511/I extract the key part:Vectors are slower than ArrayList because the vectors themselves are synchronized, and ArrayList is notT
