示例#1

文件： EigenIntegration_impl.hpp 项目： 0x0all/madlib

ArrayType*
VectorToNativeArray(const Eigen::MatrixBase<Derived>& inVector) {
    typedef typename Derived::Scalar T;
    typedef typename Derived::Index Index;

    MutableArrayHandle<T> arrayHandle
        = defaultAllocator().allocateArray<T>(inVector.size());

    T* ptr = arrayHandle.ptr();
    for (Index el = 0; el < inVector.size(); ++el)
        *(ptr++) = inVector(el);

    return arrayHandle.array();
}
