Trying fmincon and plotting the max-line from the partial derivatives.
The max locations are calculated on every curve segments;
the global optimum is found by a solver on a greater area.
little structurizaqtion:
 - getObjFunc()
 - getObjFuncMaxForLine()
 - plotObjFuncOnCurveAndMax()
improved plotCurve()
plot some objfuncs with its optimum
main2: OutputFcn called from solver
comments at the solver call

objfunc = smallest eigenvalue of the inverse covariance matrix;
it has to be maximized
