Example: Function call: log_sum(matrix_1).

 

matrix_1:

 

 

at point_1:

 

 

MATLAB code (.\Aorda\PSG\MATLAB\Examples\Functions\Func_value_log_sum.m) for function calculation:

 

%Calculation of functions with PSG Subroutine 'functionvalue'

%Define data:

H = [1 4 8 3];

a = [0.1;0.91;1.1;10];

%Calculate log_sum function at point 'a':

[val1] = functionvalue('log_sum', [], H, [], [], a);

%Display function value:

disp(sprintf('functionvalue = %g', val1));

%=======================================================================

%Calculation of functions with PSG Subroutine 'mpsg_function_value'

%Create the PSG matrix 'matrix_1'(structure containing header and matrix body) and pack it to structure 'iargstruc_arr':

iargstruc_arr(1) = matrix_pack('matrix_1', H, [], [], []);

%Create the PSG point 'point_1'(structure containing header and matrix body) and pack it to structure 'iargstruc_arr':

iargstruc_arr(2) = point_pack('point_1', a', []);

%Calculate log_sum function at point 'point_1':

[val2] = mpsg_function_value('log_sum(matrix_1)','point_1',iargstruc_arr);

%Display function value:

disp(sprintf('mpsg_function_value = %g', val2));

 

Program output:

 

functionvalue = 4.99041

mpsg_function_value = 4.99041
