Plot Variables of many .m files in Main.m file

I have Many M files say `GAdeferrableload,GAnondeferrableload,GAinterruptibleload,GAnoninterruptibleload,GAmustrunload,WDO_SG_Code_PL_test1mdeferrableload,WDO_SG_Code_PL_test1mnondeferrableload,WDO_SG_Code_PL_test1minterreuptibleload,WDO_SG_Code_PL_test1mnoninterreuptibleload,WDO_SG_Code_PL_test1mmustrunload,GA_WDO_DeferrableLoad,GA_WDO_NonDeferrableLoad,GA_WDO_InterruptibleLoad,GA_WDONonInterruptibleLoad,GA_WDOMustRunLoad, and one `Mainfile.m file which are all script files and I want to plot variables of all M files in `Mainfile.m` like % Unscheduled and scheduled cost of ga

    unscheduledcostga=(sum_unschedule_costdlaga+sum_unschedule_costndlaga+sum_unschedule_costilaga+sum_unschedule_costnilaga)/4;
    scheduledcostga=(sum_schedule_costdlaga+sum_schedule_costndlaga+sum_schedule_costilaga+sum_schedule_costnilaga)/4;
    % Unscheduled and scheduled cost of wdo
    % unscheduledcostwdo=(sum_unscheduledcostdlawdo+sum_unscheduledcostndlawdo+sum_unscheduleilawdo+sum_unschedulenilawdo)/4;
    % scheduledcostwdo=(sum_E_Cost_SSdlawdo+sum_E_Cost_SSndlawdo+sum_E_Cost_SSilawdo+sum_E_Cost_SSnilawdo)/4;
    % % Unscheduled and scheduled cost of hybrid
    % unscheduledcosthybrid=(sum_unscheduledcostdlahybrid+sum_unschedulendlahybrid+sum_unscheduleilahybrid+sum_unschedulenilahybrid)/4;
    % scheduledcosthybrid=(sum_E_Cost_SSdlahybrid+sum_E_Cost_SSndlahybrid+sum_E_Cost_SSilahybrid+sum_E_Cost_SSnilahybrid)/4;

    figure
    grid on
    bar(1,unscheduledcostga,.2,'blue')              % unscheduled cost by ga
    hold on
    bar(2,scheduledcostga,.2,'magenta');            % scheduled cost by ga
    hold on
    % bar(3,unscheduledcostwdo,.2,'green');         % unscheduled cost by wdo
    % hold on

    set(gca, 'XTick',1:1:6, 'XTickLabel',{'Unscheduled Cost GA','Scheduled Cost GA','Unscheduled Cost WDO','Scheduled Cost WDO','Unscheduled Cost Hybrid','Scheduled Cost Hybrid'})%'Scheduled with PV', 'Generation Cost',
    ylabel('Energy Cost($)')
    hold on

    When I do it, I got 

    Undefined function or variable 'sum_unschedule_costdlaga'.

    Error in Mainfile (line 123)
    unscheduledcostga=(sum_unschedule_costdlaga+sum_unschedule_costndlaga+sum_unschedule_costilaga+sum_unschedule_costnilaga)/4;

 Please any suggestion?

please site owner are requested don't delete or hold my question or any of its contents,I want to do it via .mat files because via functions it will be a lengthy process,in above each file at-least 500 variables exist

Answer 1

[Stalin Samuel]

• You have to create each m file as function Create Functions in Files
• For Each M file assign a output variable
• Call all files(i.e. function files ) from a main file
• Now you can plot all the variables

[Zafar Iqbal]

these all files i.e i have 20 atleast m files which are script files and contains code which do something if i run each file separately they run ok and gave plots but i want to put all m files name in other m file called main.m which is also a script file and want to make all plots in main.m files and access all variables in plots in main.m from all those m files which are made separately and their names are written in main.m file but i donot want to do it via functions please can you gave example of code how i can do it via functions?

[Zafar Iqbal]

there are a lot of variables in one m files out of 20 m files refer to your point "For Each M file assign a output variable" how can i access all these all variables in assigned output variable if i make a function for each m file ?i want to access 20 m files in one main.m file and each m file out of 20 contains many variables which are required to be plotted.
