MOSEK_OPTIONS Sets options for MOSEK.
OPT = MOSEK_OPTIONS
OPT = MOSEK_OPTIONS(OVERRIDES)
OPT = MOSEK_OPTIONS(OVERRIDES, FNAME)
OPT = MOSEK_OPTIONS(OVERRIDES, MPOPT)
Sets the values for the param struct normally passed to MOSEKOPT.
Inputs are all optional, second argument must be either a string
(FNAME) or a struct (MPOPT):
OVERRIDES - struct containing values to override the defaults
FNAME - name of user-supplied function called after default
options are set to modify them. Calling syntax is:
MODIFIED_OPT = FNAME(DEFAULT_OPT);
MPOPT - MATPOWER options struct, uses the following fields:
opf.violation - used to set opt.MSK_DPAR_INTPNT_TOL_PFEAS
verbose - not currently used here
mosek.lp_alg - used to set opt.MSK_IPAR_OPTIMIZER
mosek.max_it - used to set opt.MSK_IPAR_INTPNT_MAX_ITERATIONS
mosek.gap_tol - used to set opt.MSK_DPAR_INTPNT_TOL_REL_GAP
mosek.max_time - used to set opt.MSK_DPAR_OPTIMIZER_MAX_TIME
mosek.num_threads - used to set opt.MSK_IPAR_INTPNT_NUM_THREADS
mosek.opts - struct containing values to use as OVERRIDES
mosek.opt_fname - name of user-supplied function used as FNAME,
except with calling syntax:
MODIFIED_OPT = FNAME(DEFAULT_OPT, MPOPT);
mosek.opt - numbered user option function, if and only if
mosek.opt_fname is empty and mosek.opt is non-zero, the value
of mosek.opt_fname is generated by appending mosek.opt to
'mosek_user_options_' (for backward compatibility with old
MATPOWER option MOSEK_OPT).
Output is a param struct to pass to MOSEKOPT.
There are multiple ways of providing values to override the default
options. Their precedence and order of application are as follows:
With inputs OVERRIDES and FNAME
1. FNAME is called
2. OVERRIDES are applied
With inputs OVERRIDES and MPOPT
1. FNAME (from mosek.opt_fname or mosek.opt) is called
2. mosek.opts (if not empty) are applied
3. OVERRIDES are applied
Example:
If mosek.opt = 3, then after setting the default MOSEK options,
MOSEK_OPTIONS will execute the following user-defined function
to allow option overrides:
opt = mosek_user_options_3(opt, mpopt);
The contents of mosek_user_options_3.m, could be something like:
function opt = mosek_user_options_3(opt, mpopt)
opt.MSK_DPAR_INTPNT_TOL_DFEAS = 1e-9;
opt.MSK_IPAR_SIM_MAX_ITERATIONS = 5000000;
See the Parameters reference in "The MOSEK optimization toolbox
for MATLAB manaul" for details on the available options. You may also
want to use the symbolic constants defined by MOSEK_SYMBCON.
