C矩阵行列式计算-内存泄漏

我的计算矩阵行列式的程序仍然存在内存泄漏。我不知道怎么修理它。我已经标记了valgrind发现无效的代码行。矩阵是从文本文件加载的。文件示例（第一个数字是矩阵的大小）：

3.
1 2 3 
4 5 6
7 8 9

代码：

#包括

无效显示矩阵（双**矩阵，整数n）{\
puts（“显示矩阵”）；
int i，j；
对于（i=0；i您的第99行是无用的：

  double** minor = (double**)calloc(n, sizeof(double*));  // <---- Line 99

double**minor=（double**）calloc（n，sizeof（double*）；//2
：内存泄漏：指针被覆盖

删除它，你会没事的

  double** minor = (double**)calloc(n, sizeof(double*));  // <---- Line 99
