syevd_scratchpad_size
Computes size of scratchpad memory required for syevd (USM Version) function. This routine belongs to the oneapi::mkl::lapack namespace.
Description
Computes the number of elements of type T the scratchpad memory to be passed to the syevd (buffer or USM version) function must be able to hold.
API
Syntax
namespace oneapi::mkl::lapack {
  template<typename T>
  std::int64_t syevd_scratchpad_size(sycl::queue &queue,
  mkl::job jobz,
  mkl::uplo uplo,
  std::int64_t n,
  std::int64_t lda)
} 
    
   Input Parameters
- queue
 -  
     
Device queue where calculations by the syevd (buffer or USM version) function will be performed.
 - jobz
 -  
     
Must be job::novec or job::vec.
If jobz = job::novec, then only eigenvalues are computed.
If jobz = job::vec, then eigenvalues and eigenvectors are computed.
 - uplo
 -  
     
Must be uplo::upper or uplo::lower.
If uplo = job::upper, a stores the upper triangular part of A.
If uplo = job::lower, a stores the lower triangular part of A.
 - n
 -  
     
The order of the matrix A (0 ≤ n).
 - lda
 -  
     
The leading dimension of a. Must be at least max(1,n).
