selects a set of SIF problems
pbs=sifselect(DB,options)
string, path of the directory containing CLASSF.DB database file or the database file full path
vector of 3 chars [objective constraints regularity]
char with possible values:
"n" no objective function
"c" constant objective function
"c" constant objective function
"l" linear objective function
"q" quadratic objective function
"s" sum of squares objective function
"o" more general objective function
char with possible values:
"u" no constraints
"x" constraints as fixed variables
"b" bound constraints
"n" constraints represented by adjacency matrix
"l" linear constraints
"q" quadratic constraints
"o" more general constraints
char with possible values:
"r" problem is regular
"i" problem is irregular
column vector of strings, the corresponding problem names
Given a CLASSF.DB database file and selection options pbs=sifselect(DB,options) returns the problems listed in the databases which mach the selction.
