Access to storage¶
The storage of all the classes can be accessed through the data()
method, which is complemented with the iterators begin()
and end()
. Consider the following examples
Creating a cppmat-object¶
Copy constructor¶
#include <cppmat/cppmat.h>
using T2 = cppmat::cartesian3d::tensor2<double>;
int main()
{
std::vector<double> data(3*3);
for ( size_t i = 0 ; i < 3*3 ; ++i )
data[i] = static_cast<double>(i);
T2 A = T2::Copy(data.begin(), data.end());
std::cout << "A = " << A << std::endl;
}
std::copy¶
#include <cppmat/cppmat.h>
using T2 = cppmat::cartesian3d::tensor2<double>;
int main()
{
std::vector<double> data(3*3);
for ( size_t i = 0 ; i < 3*3 ; ++i )
data[i] = static_cast<double>(i);
T2 A;
std::copy(data.begin(), data.end(), A.begin());
std::cout << "A = " << A << std::endl;
}
