Parameters

uplo
Type: SystemChar
'U': A is upper triangular, 'L': A is lower triangular
transA
Type: SystemChar
'N': A * X = B (No transpose); 'T': A**T * X = B (Transpose), 'T': A**T * X = B (Transpose)
diag
Type: SystemChar
'N' arbitrary diagonal elements, 'U' unit diagonal
N
Type: SystemInt32
order of A
nrhs
Type: SystemInt32
number of right hand sides - columns of matrix B
A
Type: ILNumericsfcomplex*
square matrix A
LDA
Type: SystemInt32
spacing between columns for A
B
Type: ILNumericsfcomplex*
(input/output) on input: right hand side, on output: solution x
LDB
Type: SystemInt32
spacing between columns for B
info
Type: SystemInt32
(output) 0: success; < 0: illigal argument, > 0: A is sinular having a zero on the i-th diagonal element. No solution will be computed than.
