评论： chamant swarup 2019-5-5

Iam completely new to GUI and programming any correction to code is appreciated !

I am trying to assign the value of variable x in another matfile named "main_file_Run" to static boxs !

For eg: varible x =[32, 7] and keeps updating and i when i press pushbutton it should run the matlab file needs to assign the values upated in x matrix i.e 32 nd 7 to two respective static boxes with tag names text3 and tex4 respectively.

function pushbutton1_Callback(hObject, eventdata, handles)
% a= get(handles.main_file_Run(variable x),'string');
% (set(handles.text3,'string'))
main_file_Run();

I know i completely missed the logic here ! I am only able to run the program by calling the matfile but have no clue what to do to update the values from the variables x to the two static boxes .Firstly how do we load the varible ? should we save it as text file then kind of load into the call back of pushbutton ?

thanks in advance!

make sure your function main_file_run() actually has an output, so in that function:

function x = main_file_run()
% blah blah blah
x = (some answer from calculations above)
end

then in your pushbutton callback:

function pushbutton1_Callback(hObject, eventdata, handles)
x = main_file_Run();
set(findobj(gcf,'Tag','text3'),'String',num2str(x(1)))
set(findobj(gcf,'Tag','text4'),'String',num2str(x(2)))
end

note :

how the static text boxes display strings and not numerics.
I'm finding the static textboxes through their given Tag properties (i hope you did mean this, and not their variable names defined in another function) in the current figure (gcf))
For future reference, if you don't want to use gcf and want to look at a particular figure, you can try do do:

f = findobj(groot,'Name','FigureTitle') % returns figure handle of figure with specified name

i did not understand the usage of gcf in this problem !

Firstly my main_file_Run looks like this , on simlation it outputs the two values of X = [ 32 7 ]

these values keep updating until one final optimal value is reached . since these values will be saved to workspace as variable x , my idea was to pull those numbers and update in two static boxes with tag names text 3 and 4 by that i mean their name in property inspector used for manipulations. so do u still mean the same ? will the above code work ?

function main_file_Run
clear
close all;clc;format compact;
global ASC
%global iter
ASC=0;
%iter=0;
fun = @economic_analysis;  %fitness calculation function  
nvar = 2; % A 2-D problem
lb = [20  4]; % lower Bounds for solar,  and battery respectively
ub = [35 8];% upper bounds
% ps = parallel.Settings;
% ps.Pool.AutoCreate = false;
options = optimoptions(@particleswarm,'OutputFcn',@pswplotranges);
options = optimoptions('particleswarm', 'UseParallel', false , 'UseVectorized', false,'MaxIterations',10000);
rng default % For reproducibility
[x,fval,eflag,output] = particleswarm(fun,nvar,lb,ub,options)
% for winter
m1=1;
plot_statistics(x,m1,1)
% for summer
m1=11521;
plot_statistics(x,m1,0)
%for Rest ofthe season
m1=5665;
plot_statistics(x,m1,0)
end

no , when i closed the specific function it asked me to close all the nested functions iniside but the number of errors doubled this time , i have no clue

Somewhere some function is closing your GUI. You can use the debugger to set a breakpoint and go through your code line by line to see where your GUI is being closed.

X = main_file_Run();
handles.text3.String = num2str(X(1));
handles.text4.String = num2str(X(2));

I changed the code to this and it worked fine !!

thanks for the help people !!
