Running the code from lbfgsAdd.m and I get the error bfgsAdd (line 21): lbfgsAddC(y,s,Y,S,ys,int32(lbfgs_end)) -- Unrecognized function or variable 'lbfgsAddC'. How do I solve this?

Can't you do what is suggested in my above link:

solve it with modifying ex1a_linreg.m line 46 to

options = struct('useMex',0);

In this case, MATLAB will just use the .m file, not the mex-file.

I ended up solving this by running mex lbfgsAddC.c and then moving the output of that to the same folder as lbfgsAdd.m and it worked. Thanks for the help though!
