Initializing help system before first use

problem.writeSol

Purpose
Writes the current solution to a CSV format ASCII file, problem_name .asc (and .hdr).
Topic areas
File IO, Solution, Optimizer
Synopsis
problem.writeSol(filename="", flags="")
Arguments
filename 
A string of up to MAXPROBNAMELENGTH characters containing the file name to which the solution is to be written. If omitted, the default problem_name will be used. The extensions .hdr and .asc will be appended.
flags 
Flags to control which optional fields are output:
s 
sequence number;
n 
name;
t 
type;
b 
basis status;
a 
activity;
c 
cost (columns), slack (rows);
l 
lower bound;
u 
upper bound;
d 
dj (column; reduced costs), dual value (rows; shadow prices);
r 
right hand side (rows).
If no flags are specified, all fields are output.
Additional flags:
p 
outputs in full precision;
q 
only outputs vectors with nonzero optimum value;
x 
output the current LP solution instead of the MIP solution;
z 
compress the output file.
Related controls
Double
OUTPUTTOL 
Tolerance on print values.

String
OUTPUTMASK 
Mask to restrict the row and column names output to file.

Further information
1. This function currently does not apply to general nonlinear problems.
2. The command produces two readable files: filename.hdr (the solution header file) and filename.asc (the CSV format solution file). The header file contains summary information, all in one line. The ASCII file contains one line of information for each row and column in the problem. Any fields appearing in the .asc file will be in the order the flags are described above. The order that the flags are specified by the user is irrelevant.
3. Additionally, the mask control OUTPUTMASK may be used to control which names are reported to the ASCII file. Only vectors whose names match OUTPUTMASK are output. OUTPUTMASK is set by default to " ????????", so that all vectors are output.
