Next, you ensure that your atomic variable is initialized using the ATOMIC_INIT symbolic constant.

接下来，需确保您的原子变量使用ATOMIC_INIT符号常量进行了初始化。

However, as each entry in the determinant is symbolic, that is, a polynomial in variable(s), this leads to the intermediate expression swell(or explosion) problem in the expansion of determinant.

但是，由于行列式中的元素通常是符号化的，即其中每个元素都是关于变元（或参数）的多项式，导致行列式展开时的中间计算过程膨胀（甚至爆炸）。
