Function Documentation

CLASET_BAND initializes the main diagonal of dA to DIAG, and the K-1 sub- or super-diagonals to OFFDIAG.

Parameters

[in]	uplo	magma_uplo_t Specifies the part of the matrix dA to be set. = MagmaUpper: Upper triangular part = MagmaLower: Lower triangular part
[in]	m	INTEGER The number of rows of the matrix dA. M >= 0.
[in]	n	INTEGER The number of columns of the matrix dA. N >= 0.
[in]	k	INTEGER The number of diagonals to set, including the main diagonal. K >= 0. Currently, K <= 1024 due to CUDA restrictions (max. number of threads per block).
[in]	offdiag	COMPLEX Off-diagonal elements in the band are set to OFFDIAG.
[in]	diag	COMPLEX All the main diagonal elements are set to DIAG.
[in]	dA	COMPLEX array, dimension (LDDA,N) The M-by-N matrix dA. If UPLO = MagmaUpper, only the upper triangle or trapezoid is accessed; if UPLO = MagmaLower, only the lower triangle or trapezoid is accessed. On exit, A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n where i != j, abs(i-j) < k; and A(i,i) = BETA, 1 <= i <= min(m,n)
[in]	ldda	INTEGER The leading dimension of the array dA. LDDA >= max(1,M).
[in]	queue	magma_queue_t Stream to execute CLASET in.

DLASET_BAND initializes the main diagonal of dA to DIAG, and the K-1 sub- or super-diagonals to OFFDIAG.
