Will smart pointer automatically release space hold by array?

If I apply memory by shared_ptr<double> p(new int);, the space applied will be automatically released once the use_count of p turns to 0. But if I apply for an array memory by shared_ptr<double> p(new int[10]);, will the whole array memory be released, or only the space of the first value is released(and cause potential memory leak)?

Matrix::Matrix(size_t m, size_t n) {
  shared_ptr<double> data_(new double[m * n]);
  m_ = m;
  n_ = n;
}
