nag_quad_opt_get (d01zlc) is used to query the current value associated with an optional argument for nag_quad_1d_gen_vec_multi_rcomm (d01rac)
nag_quad_opt_get (d01zlc) is used to query the current value associated with optional arguments. It is necessary to initialize optional argument arrays, iopts
, using nag_quad_opt_set (d01zkc)
before any optional arguments are queried.
nag_quad_opt_get (d01zlc) will normally return either an integer, real or character value dependent upon the type associated with the optional argument being queried. Some real and integer optional arguments also return additional information in cvalue
. Whether the optional argument queried is of integer, real or character type, and whether additional information is returned in cvalue
, is indicated by the returned value of optype
Information on optional argument names and whether these options are real, integer or character can be found in Section 11
in nag_quad_1d_gen_vec_multi_rcomm (d01rac).
See the example programs associated with the problem solving function you wish to use for a demonstration of how to use nag_quad_opt_get (d01zlc).
