   Purpose   
   =======</pre><p>
<pre>   <a class="el" href="dsp__blas2_8c.html#221dfb4c5cbc550095a989c61fec4993">sp_dgemv()</a>  performs one of the matrix-vector operations   
      y := alpha*A*x + beta*y,   or   y := alpha*A'*x + beta*y,   
   where alpha and beta are scalars, x and y are vectors and A is a
   sparse A-&gt;nrow by A-&gt;ncol matrix.</pre><p>
<pre>   Parameters   
   ==========</pre><p>
<pre>   TRANS  - (input) char*
            On entry, TRANS specifies the operation to be performed as   
            follows:   
               TRANS = 'N' or 'n'   y := alpha*A*x + beta*y.   
               TRANS = 'T' or 't'   y := alpha*A'*x + beta*y.   
               TRANS = 'C' or 'c'   y := alpha*A'*x + beta*y.</pre><p>
<pre>   ALPHA  - (input) double
            On entry, ALPHA specifies the scalar alpha.</pre><p>
<pre>   A      - (input) SuperMatrix*
            Matrix A with a sparse format, of dimension (A-&gt;nrow, A-&gt;ncol).
            Currently, the type of A can be:
                Stype = NC or NCP; Dtype = SLU_D; Mtype = GE. 
            In the future, more general A can be handled.</pre><p>
<pre>   X      - (input) double*, array of DIMENSION at least   
            ( 1 + ( n - 1 )*abs( INCX ) ) when TRANS = 'N' or 'n'   
            and at least   
            ( 1 + ( m - 1 )*abs( INCX ) ) otherwise.   
            Before entry, the incremented array X must contain the   
            vector x.</pre><p>
<pre>   INCX   - (input) int
            On entry, INCX specifies the increment for the elements of   
            X. INCX must not be zero.</pre><p>
<pre>   BETA   - (input) double
            On entry, BETA specifies the scalar beta. When BETA is   
            supplied as zero then Y need not be set on input.</pre><p>
<pre>   Y      - (output) double*,  array of DIMENSION at least   
            ( 1 + ( m - 1 )*abs( INCY ) ) when TRANS = 'N' or 'n'   
            and at least   
            ( 1 + ( n - 1 )*abs( INCY ) ) otherwise.   
            Before entry with BETA non-zero, the incremented array Y   
            must contain the vector y. On exit, Y is overwritten by the 
            updated vector y.</pre><p>
<pre>   INCY   - (input) int
            On entry, INCY specifies the increment for the elements of   
            Y. INCY must not be zero.</pre><p>

   =======</pre><p>
<pre>   <a class="el" href="dsp__blas2_8c.html#aa92ff654356fe62f70ebef5815627e4">sp_dtrsv()</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><p>

<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.
