C++ is_scalar用法及代码示例 C++ STL 的 std::is_scalar 模板用于检查给定类型是否为标量类型。它返回一个显示相同的布尔值。 用法: template < class T > structis_scalar; 参数:此模板接受单个参数 T(Trait 类)来检查 T 是否为标量类型。 返回值:此模板返回一个布尔值,如下所示: True:如果类型是标量类型...
若T为标量类型(即可有 cv 限定的算术、指针、指向成员指针、枚举或std::nullptr_t类型),则提供等于true的成员常量value。对于任何其他类型,value为false。 添加is_scalar或is_scalar_v(C++17 起)的特化的程序行为未定义。 模板形参 T-要检查的类型

function y = mypolyval(c0,c,x) if isempty(c) y = c0; else y = c0 + power(x, 1:numel(c))*c(:); end The case y = c0 + c*x is already covered by the else. And you can use matrix multiplication of a row and a column vector r*c ins...

aAt point C, the scalar dissipation rate is significant because of lower diffusivity coefficient and stronger turbulent straining in the extinguished flame (Fig. 11b). The flame extinction is also significant at point D. However, the temperature and consequently the molecular diffusivity and scalar ...
rate is relatively high. Also at point C, the OH production rate is nearly zero (Fig. 13c), an indication of flame extinction at this point. Interestingly, the maximum value of the scalar dissipation rate occur at point D and not at C. 相反,而标量散逸率相对地高,在点C,温度是最低的...
