%Calculation of function with PSG Subroutine 'functionvalue'

%Calculate avg_pm_ni_dev_g function with parameter 0 at point 'a':

val1 = functionvalue('avg_pm_ni_dev_g', alpha, {H1 ,H2}, {c1 ,c2}, {p1 ,[]}, 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':

toolboxstruc_arr(1) = tbpsg_matrix_pack('matrix_1', H1, [],  c1, p1);

%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 avg_pm_ni_dev_g function with parameter 0 at point 'point_1':

val2 = tbpsg_function_value('avg_pm_ni_dev_g(parameter_alpha,matrix_1,matrix_2)','point_1',toolboxstruc_arr);

%Display function value:

%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',...

'  avg_pm_ni_dev_g(parameter_alpha,matrix_1,matrix_2)',...

' ');

%Create Subroutine:

tbpsg_create_user_subroutine(problem_statement,toolboxstruc_arr,'.\','calculate_avg_pm_ni_dev_g');

%Uncomment section to call the user subroutine 'calculate_avg_pm_ni_dev_g':

%{

[solution_str,outargstruc_arr] = calculate_avg_pm_ni_dev_g(H1,matrix_1_vars,c1,p1,H2,matrix_2_vars,c2,a,point_1_vars,alpha);

%Extract function value from the solution report:
