Function Documentation

magma_int_t magma_cswap_batched ( magma_int_t  n,
magmaFloatComplex **  x_array,
magma_int_t  incx,
magma_int_t  step,
magma_int_t **  ipiv_array,
magma_int_t  batchCount,
magma_queue_t  queue 
)

cswap two row in x.

index (ipiv[step]-1)-th and index step -th

This is an internal routine that might have many assumption.

Parameters
[in]nINTEGER On entry, n specifies the size of vector x. n >= 0.
[in]x_arrayArray of pointers, dimension (batchCount). Each is a COMPLEX array of dimension
[in]incxSpecifies the increment for the elements of X. INCX must not be zero.
[in]stepINTEGER The starting address of matrix C in A. LDDA >= max(1,M).
[out]ipiv_arrayArray of pointers, dimension (batchCount), for corresponding matrices. Each is an INTEGER array, dimension (min(M,N)) The pivot indices; for 1 <= i <= min(M,N), row i of the matrix was interchanged with row IPIV(i).
[in]batchCountINTEGER The number of matrices to operate on.
[in]queuemagma_queue_t Queue to execute in.
