Scilab Function usetup - unconstrained tool, set up strating point, and bounds
Calling Sequence
- [X,BL,BU] = usetup(outsdif_path)
Parameters
- outsdif_path
: string the path of the problem relative OUTSDIF.d file (see
)
- X
: real vector, starting point of the optimization.
- BL
: real vector, lower bound on the variables.
- BU
: real vector, upper bound on the variables.
Description
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.
Examples
sifdecode(p+'sif/BROWNDEN.SIF',TMPDIR+'/BROWNDEN')
buildprob(TMPDIR+'/BROWNDEN')
[X,BL,BU]=usetup(TMPDIR+'/BROWNDEN/OUTSDIF.d')
