Triangular solve

 

A

Array whose upper or lower triangle, as specified by

 

 

uplo, contains the unit, non-unit, upper or lower

 

 

triangular matrix A. The matrix size is indicated by

 

 

SIDE:

 

 

BLAS_LEFT_SIDE A is an m-by-mmatrix

 

 

BLAS_RIGHT_SIDE A is an n-by-nmatrix

 

LDA

Leading dimension of array A.

 

 

For SIDE = BLAS_LEFT_SIDE, and lda < 1 or lda < m,

 

 

an error flag is set and passed to the error handler.

 

 

For SIDE = BLAS_RIGHT_SIDE, and lda < 1 or lda < n,

 

 

an error flag is set and passed to the error handler.

 

B

Array containing the m by n matrix B. The

 

 

representation of the matrix entry bi,j in B is denoted

 

 

by B(i, j) for all (i, j) in the interval

 

 

[0...m - 1] x [0...n - 1].

 

LDB

Leading dimension of array B.

 

 

For SIDE = BLAS_LEFT_SIDE, and ldb < 1 or ldb < m,

 

 

an error flag is set and passed to the error handler.

 

 

For SIDE = BLAS_LEFT_SIDE, and ldb < 1 or ldb < m,

 

 

an error flag is set and passed to the error handler.

Output

B

The updated m-by-nmatrix replaces the input.
