This contribution is made in order to calculate the maximum likelihood contour plots of any function. Just replace the <<fcnObjfun>> file with your function change some basic settings in the <<Example>> file and there you go. The objective function has to return a scalar. There are two settings only: the range of the parameter to be varied around the base case value [%] and the resolution of this range [%].

Additional parameters of the objective function can be passed in the form of a vector or structure. I provided also some results of this contribution, the JPEG files.

EXAMPLE ==============================
% base case coefficients
BCcoeff = [ -2 4 -6 8];
% set the sensitivity range in %: e.g 30% around base case value
settings.Range = 30;
% sensitivity grid resolution
settings.step = 1;
% contour plot setting
settings.CplotRange = [ 50:2:100];
% additional parameter vector = []
param =[];
% call function to calculate matrix Z
outStr = fcnSensitivityRun_3D('fcnObjfun', BCcoeff, settings, param)

% call function fcnMLPlot(outStr) to %plot the results
% it was split in two functions because the calculation of matrix Z can
% take long time, e.g. for ODE systems %and if you want to change the
% contour plot settings then you dont %need to recalculate Z.

% for e.g. you can change again the contour plots setting
%
outStr.setts.CplotRange = [ 20:10:100];
fcnMLPlot(outStr)

Additional toolboxes needed: Communications TBX, vec2mat function.
