Solve triangular system

diag

Specifies whether the matrix is unit triangular, that is,

 

aii = 1, or not:

 

 

’N’ or ’n’

The diagonal of A is stored in the

 

 

array

 

’U’ or ’u’

The diagonal of A consists of unstored

 

 

ones

 

When diag is supplied as ’U’ or ’u’, the diagonal

 

elements are not referenced.

n

Number of rows and columns in matrix A, n ≥ 0. If n =

 

0, the subprograms do not reference a or x.

a

Array containing the n-by-ntriangular matrix A.

lda

The leading dimension of array a as declared in the

 

calling program unit, with lda ≥ max(n,1).

x

Array of length lenx = (n−1)⋅incx+1 containing the

 

right-hand-side n-vector x.
