Error in running the available examples

[ghost]

Hello,

I downloaded the available optragen toolbox, then I obtained the available snopt files with a student precompiled license.

why i try to run one of the available examples, bang bang control for example,
i get the following errors

Error using snopt (line 141)
Not enough input arguments.

Error in BangBangControl (line 76)
[x,F,inform] =
snopt(init',xlow,xupp,[0;nlp.LinCon.lb;nlp.nlb],[Inf;nlp.LinCon.ub;nlp.nub],'ocp2nlp_cost_and_constraint');

however when i check if matlab can actually find snopt by typing

exist('snopt','file')

ans =

 2

any idea how to resolve the not enough input arguments issue ? the results i get are attached in a picture

I am using your toolbox for motion planning of an autonomous underwater vehicle

Thank you

The SNOPT matlab interface has changed. The call to snopt should be:
snopt(x,xlow,xupp,xmul,xstate,F,Flow,Fupp,Fmul,Fstate,userfun);

Optragen doesn't have the xmul,xstate and F,Fmul,Fstate inputs. Add these input arrays and it should work. Arrays of zero will be fine, as long as the x* vectors and the F* vectors are the same lengths).

(I'll look into modifying the SNOPT interface to accept a call with empty vectors as input for the *mul and *state vectors -- but I can't remove them completely.)
