Initializing help system before first use

loadlp

Purpose
Enables the user to pass a matrix directly to the Optimizer, rather than reading the matrix from a file.
Synopsis
loadlp(
prob,
probname,
rowtype,
rhs,
rng,
objcoef,
start,
collen,
rowind,
rowcoef,
lb,
ub,
ncols = x_max_vec_length(objcoef, lb, ub),
nrows = x_max_vec_length(rowtype, rhs, rng)
)
Arguments
prob 
The current problem.
probname 
A string of up to MAXPROBNAMELENGTH characters containing a names for the problem.
rowtype 
Character array of length nrows containing the row types:
L
indicates a <= constraint;
E
indicates an = constraint;
G
indicates a >= constraint;
R
indicates a range constraint;
N
indicates a nonbinding constraint.
rhs 
Double array of length nrows containing the right hand side coefficients of the rows.
rng 
Double array of length nrows containing the range values for range rows.
objcoef 
Double array of length ncols containing the objective function coefficients.
start 
Integer array containing the offsets in the rowind and rowcoef arrays of the start of the elements for each column.
collen 
Integer array of length ncols containing the number of nonzero elements in each column.
rowind 
Integer array containing the row indices for the nonzero elements in each column.
rowcoef 
Double array containing the nonzero element values; length as for rowind.
lb 
Double array of length ncols containing the lower bounds on the columns.
ub 
Double array of length ncols containing the upper bounds on the columns.
ncols 
Number of structural columns in the matrix.
nrows 
Number of rows in the matrix (not including the objective).
Return value
The input argument prob.
