Parameters
Order
Specifies row-major (C) or column-major (Fortran) data ordering.
Uplo
Specifies whether to use the upper or lower triangle from the matrix. Valid values are 'U'
or 'L'
.
TransA
Specifies whether to use matrix A ('N'
or 'n'
) or the transpose of A ('T'
, 't'
, 'C'
, or 'c'
).
Diag
Specifies whether the matrix is unit triangular. Possible values are 'U'
(unit triangular) or 'N'
(not unit triangular).
N
A
lda
The leading dimension of matrix A
.
X
incX
Stride within X
. For example, if incX
is 7, every 7th element is used.
Discussion
Solves A*x=b
or A'*x=b
where x
and b
are elements in X
and B
.
