armadillo c++ typecast double matrix mat to float matrix fmat
如何将 mat 类型转换为 fmat。我的功能之一是返回垫子。但是为了记忆，我想将其转换为 fmat。我怎样才能输入转换它？
您可以使用 conv_to:
在矩阵类型之间进行转换
|
1
2
3
|
mat A = my_function();
fmat B = conv_to<fmat>::from(A);
fmat C = conv_to<fmat>::from(my_function());
|
或者，您可以将函数更改为模板；例如：
|
1
2
3
4
5
6
7
8
9
|
template <typename T >
Mat < T > other_function () {
return Mat < T >(4, 4);
}
…
fmat D = other_function<float>();
mat F = other_function<double>();
|
- 向量呢？例如，双向量 vec 到浮点向量 fvec？上述解决方案也适用于矢量。谢谢！！！！
