Re: [Help-glpk] Printing non-zero parts of a solution matrix

[glpk xypron]

Hello Reg,

# Generate some random data.
set S := {1..1000};
param x{S} := if Uniform01() > .99 then Uniform01() else 0;
# Print nonzero elements only.
printf {s in S: x[s] > 0 }
  "x[%d] = %f\n", s, x[s];
end;

Best regards
