get_cost_params

GET_COST_PARAMS  Returns the cost parameter struct for user-defined costs.

   -----  DEPRECATED - use PARAMS_LEGACY_COST instead  -----

   CP = OM.GET_COST_PARAMS()
   CP = OM.GET_COST_PARAMS(NAME)
   CP = OM.GET_COST_PARAMS(NAME, IDX)

   Returns the full cost parameter struct for all user-defined
   costs that incorporates all of the named cost sets added via ADD_COSTS,
   or, if a NAME is provided it returns the cost struct corresponding to
   the named set of cost rows (N still has full number of columns).

   The cost parameters are returned in a struct with the following fields:
       N      - nw x nx sparse matrix
       Cw     - nw x 1 vector
       H      - nw x nw sparse matrix (optional, all zeros by default)
       dd, mm - nw x 1 vectors (optional, all ones by default)
       rh, kk - nw x 1 vectors (optional, all zeros by default)

   See also OPT_MODEL, ADD_COSTS, COMPUTE_COST.
