Get the value for the given element in an optimization object.
optimbase.get(this = NULL, key = NULL)
optimbase.histget(this = NULL, iter = NULL, key = NULL)An optimization object.
The name of the key to quiery. The list of available keys for
query with optimbase.get is: 'verbose', 'x0', 'fx0', 'xopt', 'fopt',
'tolfunabsolute', 'tolfunrelative', 'tolfunmethod', 'tolxabsolute',
'tolxrelative', 'tolxmethod', 'maxfunevals', 'maxiter', 'iterations',
'function', 'status', 'historyfopt', 'historyxopt', 'verbosetermination',
'outputcommand', 'outputcommandarg', 'numberofvariables', 'storehistory',
'costfargument', 'boundsmin', 'boundsmax', 'nbineqconst', 'logfile',
'logfilehandle', 'logstartup', and'withderivatives'.
The list of available keys for query with optimbase.histget is:
'historyxopt' and 'historyfopt'.
The iteration at which the data is stored.
Return the value of the list element key, or an error message if
key does not exist.
While optimbase.get extracts the entire content of the object element,
including historyxopt and historyfopt, optimbase.histget
only extracts the content of the history at the iteration iter.
