queue

Device queue where calculations will be performed.

uplo

Indicates how the input matrix has been factored:

If uplo=

mkl::uplo::upper

, the upper triangle

U

i

of

A

i

is stored, where

A

i

=

U

i

T

*

U

i

for real data,

A

i

=

U

i

H

*

U

i

for complex data.

If uplo=

mkl::uplo::lower

, the upper triangle

L

i

of

A

i

is stored, where

A

i

=

L

i

*

L

i

T

for real data,

A

i

=

L

i

*

L

i

H

for complex data.

n

The order of the matrices

A

i

(

0 ≤ n

).

nrhs

The number of right hand sides

(0≤nrhs)

.

lda

The leading dimension of

A

i

.

stride_a

The stride between the beginnings of matrices inside the batch array

a

.

ldb

The leading dimensions of

B

i

.

stride_b

The stride between the beginnings of matrices

B

i

inside the batch array

b

.

batch_size

Specifies the number of problems in a batch.
