optimbase_get

Returns the value for the given key.

Syntax

value = optimbase_set(opt, key)

Argument

opt

The object of TOPTIM type (tlist).

key

A string, the name of the key to set.

value

the value in function of the given key.

Description

The optimbase_get function returns the value for the given key. If the key is unknown, this function generates an error.

The list of available keys is the same as the optimbase_set function:

-funevals

The number of function evaluations is a 1-by-1 matrix of doubles, positive, integer value.

-iterations

The number of iterations is a 1-by-1 matrix of doubles, positive, integer value.

-xopt

The x optimum.

-fopt

The optimum cost function value.

-historyxopt

An array, with nbiter values, containing the history of x during the iterations.

This array is available after optimization if the history storing was enabled with the -storehistory option.

-historyfopt

An array, with nbiter values, containing the history of the function value during the iterations.

This array is available after optimization if the history storing was enabled with the -storehistory option.

-fx0

The function value for the initial guess.

-status

A string containing the status of the optimization.

-logstartup

A 1-by-1 matrix of booleans. Set to %t when the logging is started up (default -logstartup = %f).

Example

opt = optimbase_new();

// Set optimum
opt = optimbase_set(opt,"-xopt",[1.0 1.0]) ;
// Get optimum
val = optimbase_get(opt, "-xopt")

// Set function value at optimum
opt = optimbase_set(opt,"-fopt",1.0);
// Get function value at optimum
val = optimbase_get(opt, "-fopt")

// Set status
opt = optimbase_set(opt,"-status","maxiter");
// Get status
val = optimbase_get(opt, "-status")

opt = optimbase_destroy(opt);
