addrows

Purpose
Adds rows to the optimizer matrix.
Synopsis
addrows(
prob,
rowtype,
rhs,
start,
colind,
rowcoef,
rng = NULL,
nrows = x_max_vec_length(rowtype, rhs),
ncoefs = x_max_vec_length(colind, rowcoef)
)
Arguments
prob 
The current problem.
rowtype 
Character array of length nrows containing the row types:
L
indicates a <= row;
G
indicates >= row;
E
indicates an = row.
R
indicates a range constraint;
N
indicates a nonbinding constraint.
rhs 
Double array of length nrows containing the right hand side elements.
start 
Integer array of length nrows containing the offsets in the colind and rowcoef arrays of the start of the elements for each row.
colind 
Integer array of length ncoefs containing the (contiguous) column indices for the elements in each row.
rowcoef 
Double array of length ncoefs containing the (contiguous) element values.
rng 
Double array of length nrows containing the row range elements.
nrows 
Number of new rows.
ncoefs 
Number of new nonzeros in the added rows.
Return value
The input argument prob.
