Проблема реализации функции DCT библиотеки mkl

Я пытаюсь заменить функцию DCT ipp.lib с помощью функции DCT mkl.lib.
Я использовал следующий API на основе Ipp для выполнения DCT:

ippsDCTFwdInitAlloc_32f
ippsDCTFwd_32f
ippsDCTFwdFree_32f

Пример кода DCT на основе MKL для моего PFB:

#include <time.h>
#include <stdlib.h>
#include "mkl.h"int main(int argc, char* argv[]){

float *dpar;
float *out;
MKL_INT    *ipar;
MKL_INT tt_type,stat,n_1,nn;
FILE *fp,*fw,*fonce;
fp = fopen( "D:\\dump\\fileinput.txt","r" );
if(fp == NULL){
cout<<"file not created properly"<<endl;
}
DFTI_DESCRIPTOR_HANDLE handle = 0;
int n = 150; /*Hardcoded to run for my code TODO: going to change after integrating into my main codebase.As I can't attach my full fileinput.txt .So just taken n value = 150 */
nn = (MKL_INT)n;
tt_type = MKL_STAGGERED_COSINE_TRANSFORM;

n_1 = nn + 1 ;
out = (float*)malloc((n+1)*sizeof(float));
dpar= (float*)malloc((5*n_1/2+2)*sizeof(float));
ipar= (MKL_INT*)malloc((128)*sizeof(int));
s_init_trig_transform(&n_1,&tt_type,ipar,dpar,&stat);
for (int srcSize =0 ;srcSize< n ; srcSize++)
{
fscanf(fp,"%f\n",&out[srcSize]);
}
fclose(fp);
if (stat != 0)
{
printf("\n============================================================================\n");
printf("FFTW2MKL FATAL ERROR: MKL TT initialization has failed with status=%d\n",(MKL_INT)stat);
printf("Please refer to the Trigonometric Transform Routines Section of MKL Manual\n");
printf("to find what went wrong...\n");
printf("============================================================================\n");
return NULL;
}
ipar[10] = 1;    //nx, that is, the number of intervals along the x-axis, in the Cartesian case.
ipar[14] = n_1;  //specifies the internal partitioning of the dpar array.
ipar[15] = 1;    //value of ipar[14]+1,Specifies the internal partitioning of the dpar array.
s_commit_trig_transform(out,&handle,ipar,dpar,&stat);
if (stat != 0)
{
printf("\n============================================================================\n");
printf("FFTW2MKL FATAL ERROR: MKL TT commit step has failed with status=%d\n",(MKL_INT)stat);
printf("Please refer to the Trigonometric Transform Routines Section of MKL Manual\n");
printf("to find what went wrong...\n");
printf("============================================================================\n");
return NULL;
}
s_forward_trig_transform(out,&handle,ipar,dpar,&stat);
if (stat != 0)
{
printf("\n============================================================================\n");
printf("FFTW2MKL FATAL ERROR: MKL TT commit step has failed with status=%d\n",(MKL_INT)stat);
printf("Please refer to the Trigonometric Transform Routines Section of MKL Manual\n");
printf("to find what went wrong...\n");
printf("============================================================================\n");
return NULL;
}
free_trig_transform(&handle,ipar,&stat);
printf("\n===== DCT GOT OVER ======== \n");

return 0;

}

Но я не получаю правильный вывод. Я запутываюсь, что моя реализация правильна или нет.

Поскольку я не знаю, как прикрепить файл fileinput.txt, я разместил здесь содержимое файла.
Простите за это 🙁
