1.1 函数指针(Pointer to Function) 函数指针是一个指针,它指向函数的入口地址。 简单来说,就是用一个指针变量来保存函数的地址,通过这个指针可以间接地调用该函数。 如果是我们特训营学过项目3的老铁,应该非常熟悉了,我们大量回调函数的应用,就必须要用到函数指针。 1.2 指针函数(Function Returning Pointer) 指针...

The default precision of the %A and %a format specifiers was 6 in previous versions of the library. The default precision is now 13 for conformance with the C Standard. This is a runtime behavior change in the output of any function that uses a format string with %A or %a. In the ...
Fixes aberration() returning NaN vectors if the ve argument is 0. It now returns the unmodified input vector appropriately instead. Fixes unpopulated az output value in equ2hor() at zenith. While any azimuth is acceptable really, it results in unpredictable behavior. Hence, we set az to 0.0...
01-vector-add.cu 包含一个可正常运作的 CPU 向量加法应用程序。加速其 addVectorsInto 函数,使之在 GPU 上以 CUDA 核函数运行并使其并行执行工作。鉴于需发生以下操作,如您遇到问题,请参阅 解决方案。 扩充addVectorsInto 定义,使之成为 CUDA 核函数。 选择并使用有效的执行配置,以使 addVectorsInto 作为CUDA...
std::vector<std::string> v;// 此处填充 v std::cout << boost::algorithm::join(v,"") <<'\n'; Boost.Lexical_Cast Docs:http://boost.org/libs/lexical_cast Boost 前面已经介绍过。这是 Boost 的其中一个子库,提供了各种字符串与其它类型的转换。
The trunc() function truncates a number, which means returning only the integer part of the number.The trunc() function is defined in the <cmath> header file.SyntaxOne of the following:trunc(double number);trunc(float number);Parameter Values...
