### 5.1 Function setdbopts for setting options in ’database’

Function File: setdbopts ()
Function File: setdbopts (par, val, …)
Function File: setdbopts (old, par, val, …)
Function File: setdbopts (old, new)

  Create settings structure for database functions.

  When called without any input or output arguments, ’setdbopts’ prints a list of all valid optimization parameters.

  When called with one output and no inputs, return an options structure with all valid option parameters initialized to ’[]’.

  When called with a list of parameter/value pairs, return an options structure with only the named parameters initialized.

  When the first input is an existing options structure OLD, the values are updated from either the PAR/VAL list or from the options structure NEW.

  Please see individual database functions for valid settings.
