Purpose
=======</pre><pre> <a class="el" href="zsp__blas2_8c.html#a070a51d222072a18d8d6ac91381b4859" title="Solves one of the systems of equations A*x = b, or A'*x = b.">sp_ztrsv()</a> solves one of the systems of equations
A*x = b, or A'*x = b,
where b and x are n element vectors and A is a sparse unit , or
non-unit, upper or lower triangular matrix.
No test for singularity or near-singularity is included in this
routine. Such tests must be performed before calling this routine.</pre><pre> Parameters
==========</pre><pre> uplo - (input) char*
On entry, uplo specifies whether the matrix is an upper or
lower triangular matrix as follows:
uplo = 'U' or 'u' A is an upper triangular matrix.
uplo = 'L' or 'l' A is a lower triangular matrix.</pre><pre> trans - (input) char*
On entry, trans specifies the equations to be solved as
follows:
trans = 'N' or 'n' A*x = b.
trans = 'T' or 't' A'*x = b.
trans = 'C' or 'c' A^H*x = b.</pre><pre> diag - (input) char*
On entry, diag specifies whether or not A is unit
triangular as follows:
diag = 'U' or 'u' A is assumed to be unit triangular.
diag = 'N' or 'n' A is not assumed to be unit
triangular.</pre><pre> L - (input) SuperMatrix*
The factor L from the factorization Pr*A*Pc=L*U. Use
compressed row subscripts storage for supernodes,
i.e., L has types: Stype = SC, Dtype = SLU_Z, Mtype = TRLU.</pre><pre> U - (input) SuperMatrix*
The factor U from the factorization Pr*A*Pc=L*U.
U has types: Stype = NC, Dtype = SLU_Z, Mtype = TRU.</pre><pre> x - (input/output) doublecomplex*
Before entry, the incremented array X must contain the n
element right-hand side vector b. On exit, X is overwritten
with the solution vector x.</pre><pre> info - (output) int*
If *info = -i, the i-th argument had an illegal value.
