The supplied option string is invalid. Supplied value was: .
nlp1_option_stringmay be used to supply values for options to
nlp1_solve(). It is only necessary to call
nlp1_option_stringfor those arguments whose values are to be different from their default values. One call to
nlp1_option_stringsets one argument value.
Each option is defined by a single character string, of up to characters, consisting of one or more items. The items associated with a given option must be separated by spaces, or equals signs . Alphabetic characters may be upper or lower case. The string
Print Level = 1
is an example of a string used to set an option. For each option the string contains one or more of the following items:
a mandatory keyword;
a phrase that qualifies the keyword;
a number that specifies an int or float value. Such numbers may be up to contiguous characters in Fortran’s I, F, E or D formats, terminated by a space if this is not the last item on the line.
Blank strings and comments are ignored. A comment begins with an asterisk (*) and all subsequent characters in the string are regarded as part of the comment.
Printing of user-specified options is turned off by default. It may be turned on at any time using the keyword ‘List’.
Option settings are preserved following a call to
nlp1_solve()and so the keyword ‘Defaults’ is provided to allow you to reset all the options to their default values before a subsequent call to
A complete list of options, their abbreviations, synonyms and default values is given in Other Parameters for nlp1_solve.
