C++ 使用MKL DCT函数进行错误的DCT

我为基于MKL的离散余弦变换DCT代码提供8x8输入：

你能指导我找出代码中的错误吗？与其说是答案，不如说是问题。这四行对吗

ipar[10] = 1;    //nx, that is, the number of intervals along the x-axis,
ipar[11] = 1;    //ny, that is, the number of intervals along the x-axis,
ipar[14] = n_1;  //specifies the internal partitioning of the dpar array.
ipar[15] = 1;    //value of ipar[14]+1,Specifies the ... of the dpar array.

在前两种情况下，间隔数真的是1吗

---

在第四种情况下，注释说IPAR〔15〕是IPAR〔14〕＋1＝n1+1＝1＝nn+2＝n+2＝66的值，虽然我们不知道在Sy-InITI- TrutyTrimeToin中NY1发生了什么。< /P>这是C++代码，所以'C’标记应该是removedWeather Vane，无论x轴的间隔数是8，还是y轴8，正如他提到的n=64；8X8？？

ipar[10] = 1;    //nx, that is, the number of intervals along the x-axis,
ipar[11] = 1;    //ny, that is, the number of intervals along the x-axis,
ipar[14] = n_1;  //specifies the internal partitioning of the dpar array.
ipar[15] = 1;    //value of ipar[14]+1,Specifies the ... of the dpar array.
