Parameters
OrderSpecifies row-major (C) or column-major (Fortran) data ordering.
UploSpecifies whether to use the upper or lower triangle from the matrix. Valid values are 'U' or 'L'.
TransASpecifies whether to use matrix A ('N' or 'n') or the transpose of A ('T', 't', 'C', or 'c').
DiagSpecifies whether the matrix is unit triangular. Possible values are 'U' (unit triangular) or 'N' (not unit triangular).
NAldaThe leading dimension of matrix A.
XincXStride 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.
