MATLAB code (.\Aorda\PSG\MATLAB\Examples\Func_value_pm_ni_dev.m) for function calculation:
%Define data:
H1 = [1 4 8 3];
header_1 = {'x1', 'x2', 'x3', 'x4'};
c1 = -2;
H2 = [11 3 2 0];
header_2 = {'x1', 'x2', 'x3', 'x4'};

a = [1;1;1;1];
alpha = 0.35;

%Calculation of function with PSG Subroutine 'functionvalue'
%Calculate pm_ni_dev function with parameter 0.35 at point 'a':
val1 = functionvalue('pm_ni_dev', alpha, {H1 ,H2}, {c1 ,c2}, {[] ,[]}, a);
%Display function value:
disp(sprintf('functionvalue = %g', val1));

%Calculation of function with PSG Subroutine 'tbpsg_function_value'
%Create the PSG matrix 'matrix_1'(structure containing header and matrix body) and pack it to structure 'toolboxstruc_arr':

%Create the PSG matrix 'matrix_2'(structure containing header and matrix body) and pack it to structure 'toolboxstruc_arr':
toolboxstruc_arr(2) = tbpsg_matrix_pack('matrix_2', H2, [], c2, []);
%Create the PSG point 'point_1'(structure containing header and matrix body) and pack it to structure 'toolboxstruc_arr':
toolboxstruc_arr(3) = tbpsg_point_pack('point_1', a, []);
%Create the PSG parameter 'parameter_alpha' and pack it to structure 'toolboxstruc_arr':
toolboxstruc_arr(4) = tbpsg_parameter_pack('parameter_alpha', alpha);
%Calculate pm_ni_dev function with parameter 0.35 at point 'point_1':
val2 = tbpsg_function_value('pm_ni_dev(parameter_alpha,matrix_1,matrix_2)','point_1',toolboxstruc_arr);
%Display function value:
disp(sprintf('tbpsg_function_value = %g', val2));

%Creation of User Subroutine for calculating function value
%User subroutine is similar to the 'functionvalue'
%Create problem statement:
problem_statement = sprintf('%s\n',...
'calculate',...
'Point: point_1',...
' pm_ni_dev(parameter_alpha,matrix_1,matrix_2)',...
' ');
%Create Subroutine:
tbpsg_create_user_subroutine(problem_statement,toolboxstruc_arr,'.\','calculate_pm_ni_dev');
%Uncomment section to call the user subroutine 'calculate_pm_ni_dev':
