dear Joris,

the following code snippet does not work

nlp = struct('x', V, 'f', f, 'g', g);

ipopts_opts.ipopt.print_level = 0;

ipopts_opts.ipopt.print_timing_statistics = 'NO';

solver = nlpsol('solver', 'ipopt', nlp, struct('jit', true), ipopts_opts);

The error message is :

Error using casadiMEX
No matching function for overload function 'nlpsol'. Possible prototypes are:
    NLPSOL(char,char,Importer,struct)
    NLPSOL(char,char,struct:SX,struct)
    NLPSOL(char,char,struct:MX,struct)
    NLPSOL(char,char,char,struct)
You have: char, char, struct, struct, struct

Error in casadi.nlpsol (line 857)
[varargout{1:nargout}] = casadiMEX(860, varargin{:});

=====

It works if I leave away struct('jit', true).

It also works if I leave away the ipopts_opts.

How can I get work the combination ?

Many thanks in advance,

Simply merge the two option dictionaries/structures:

opts = struct;
opts.ipopt.print_level = 0;opts.ipopt.print_timing_statistics = 'NO';
opts.jit = true;

solver   = nlpsol('solver', 'ipopt', nlp, opts);
