Retrieving data from a Mosel model

mmexset.c: Using sets in Mosel (requires burglari.bim)
  • retrieve a set by its model name
  • get the set size
  • get first and last set element
  • get the name or index of a set element
mmexarr.c: Using arrays in Mosel (requires trans.bim)
  • compare index tuples
  • retrieve an array by its model name
  • get array size and number of dimensions
  • get indices of first and last array entries
  • get (value of) array entries
  • check whether an index tuple lies in the range of an array
mmexas.c: Using arrays with index sets (requires trans.bim)
  • get indexing sets of an array
  • get array type
  • enumerate array entries in usual and transposed order
  • enumerate true array entries
mmexlst.c: Using lists in Mosel (requires euler.mos and euler.dat)
  • retrieve a list by its model name
  • get the list size
  • enumerate the list elements
  • get value of list element
mmexrec.c: Using records in Mosel (requires burglar_rec.mos and burglar_rec.dat)
  • retrieve an array of records (user type) by its model name
  • retrieve the record field information (field name, type, and number)
  • enumerate the array of records
  • for each array entry (record) get the value of all its fields
mmexprob.c: Accessing problems and solution information with Mosel (requires blend2.bim)
  • export problem to a file (MPS or LP format)
  • get problem status
  • get objective function value
  • get primal/dual solution values, and constraint activity
Note that these examples require the provided mos files to be pre-compiled.
