带犰狳的整数矩阵的行列式

Question

I have a function whose parameter is const arma::imat & A . And apart from other things I want to calculate determinant of input matrix A. Therefore I did

int det = arma::det(A);

but during compilation I get following error:

error: no matching function for call to 'det'
int det = arma::det(A);

I tried google but found nothing that would address this problem. Any ideas please what might be the problem?

阅读文档，我认为您必须使用conv_to<type>::from才能调用为imat::mat定义的det 。
