problem.addqmatrix
| problem.addqmatrix | 
  Purpose
 
 Adds a new quadratic matrix into a row defined by triplets.
 
  Synopsis
 
problem.addqmatrix (irow, mqc1, mqc2, dqe)
 
  Arguments
 
| 
     irow 
     | 
     Index of the row where the quadratic matrix is to be added.
     | 
| 
     mqc1 
     | 
     First index in the triplets.
     | 
| 
     mqc2 
     | 
     Second index in the triplets.
     | 
| 
     dqe 
     | 
     Coefficients in the triplets.
     | 
  Further information
 
 1. The triplets should define the whole quadratic expression. This means that to add
 x2 + 4 xy the
 dqe arrays shall contain the coefficients 1 and 4.
 
 2. The matrix defined by
 mqc1,
 mqc2 and
 dqe should be positive semi-definite for ≤ and negative semi-definite for ≥ rows.
 
 3. The row must not be an equality or a ranged row.
