Trigonometric Transform Implementation Details

Several aspects of the
Intel® oneAPI Math Kernel Library
 TT interface are platform-specific and language-specific. To promote portability across platforms and ease of use across different languages,
Intel® oneAPI Math Kernel Library
 provides you with the TT language-specific header file to include in your code:
  • mkl_trig_transforms.h
    , to be used together with
    mkl_dfti.h
    .
  • Use of the
    Intel® oneAPI Math Kernel Library
     TT software without including the above language-specific header files is not supported.

Header File

The header file below defines the following function prototypes: 
void d_init_trig_transform(MKL_INT *, MKL_INT *, MKL_INT *, double *, MKL_INT *); 
void d_commit_trig_transform(double *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, double *, MKL_INT *);  
void d_forward_trig_transform(double *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, double *, MKL_INT *); 
void d_backward_trig_transform(double *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, double *, MKL_INT *);
		
void s_init_trig_transform(MKL_INT *, MKL_INT *, MKL_INT *, float *, MKL_INT *); 
void s_commit_trig_transform(float *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, float *, MKL_INT *);  
void s_forward_trig_transform(float *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, float *, MKL_INT *); 
void s_backward_trig_transform(float *, DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, float *, MKL_INT *); 

void free_trig_transform(DFTI_DESCRIPTOR_HANDLE *, MKL_INT *, MKL_INT *);
