link_det_minor¶
Speed Testing Gradient of Determinant by Minor Expansion¶
Prototype¶
extern bool link_det_minor(
const std::string& job ,
size_t size ,
size_t repeat ,
CppAD::vector<double>& matrix ,
CppAD::vector<double>& gradient
);
Method¶
The same template class det_by_minor is used by the different AD packages.
size¶
See the standard link specifications for size In addition, size is the number of rows and columns in matrix .
matrix¶
The argument matrix is a vector with size * size elements. The input value of its elements does not matter. The output value of its elements is the last matrix that the gradient (or determinant) is computed for.
