unconstrained tool, set up strating point, and bounds
[X,BL,BU] = usetup(outsdif_path)
string the path of the problem relative OUTSDIF.d file (see sifdecode )
real vector, starting point of the optimization.
real vector, lower bound on the variables.
real vector, upper bound on the variables.
usetup sets up the correct data structures for subsequent computations in the case where the only possible constraints are bound constraints. Those data structures are read in the file OUTSDIF.d produced by sifdecode. buildprob must be used before using usetup. A call to usetup must precede calls to other unconstrained tools.
