sytrd_scratchpad_size#
Computes size of scratchpad memory required for sytrd (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 sytrd (buffer or USM version) function must be able to hold.
API#

}
Input Parameters#
- queue
Device queue where calculations by the sytrd (buffer or USM version) function will be performed.
- uplo
Must be
uplo::upperoruplo::lower.If
uplo = uplo::upper,astores the upper triangular part ofA.If
uplo = uplo::lower,astores the lower triangular part ofA.- n
The order of the matrices
A(0 ≤ n).- lda
The leading dimension of a; at least
max(1,n).
