problem is that it can not plot x and y,(

IN GUI,i define handles.matricdata.a=1 in pushbutton1 callback function.

then in pushbutton2 callback function i use

    b=handles.matricdata.a;  
    if(b~=1)
      x=[1 2 3 4 5];
      y=[5 5 5 5 5]
     plot(x,y);   
    end

then problem is that it can not plot x and y,(if pushbutton1 is not press,then x and y must be plot )

You should write in opening function

 handles.matricdata.a=0

[vipul utsav]

in code y=y*5 should perform everytime b==1 or b==0;

    function pushbutton1
      handles.matricdata.a=1; 
    function pushbutton2
     handles.matricdata.a=0;  
     b=handles.matricdata.a;  
     if(b~=1)
      x=[1 2 3 4 5];
      y=[5 5 5 5 5]
     plot(x,y);   
    end
   y=y*5;

Have you updated handles with guidata?

guidata(hObject,handles)

Also in function pushbutton2

handles.matricdata.a=0;  
b=handles.matricdata.a;

b is always different from 1

yes , i have updated handels with 'guidata(hObject,handles)'

    function pushbutton1
      handles.matricdata.a=1; 
    function pushbutton2
     b=handles.matricdata.a;  
     if(b~=1)
      x=[1 2 3 4 5];
      y=[5 5 5 5 5]
     plot(x,y);   
    end
   y=y*5;

but when pushbutton1 is not pressed,it should plot x and y.

and when pushbutton1 is pressed,it should not plot x and y.

in above code these task is not perform.please correct it.

In your yourfilename_OpeningFcn

handles.metricdata.a=0;
guidata(hObject,handles)

Now why would that not plot when you just set the value to 0 and you're checking if it's not equal to 1. It must go into the if statement. But this is bad code in several ways. What's the point of setting it to 1 in pushbutton1's callback? Why have an "if" in pushbutton2's callback when you directly assign it so you know what the state will be? The if is not necessary in that case. Why do you multiply y by 5? Think about it. If you don't enter the "if" then y will be undefined and it will throw an error. (Though I've already said that you will enter the if because of strange coding.) So in that case, just set y = [25 25 25 25 25] and be done with it.

i post code just for examples but my main task of pushbuttton1 and pushbutton2 is different. i want that pushbutton2 is display the status of pushbutton1 that whether pushbutton1 is pressed or not? (i.e if pushbutton1 has been pressed and then after i press pushbutton2,it display message 'pb1 is press' using pushbutton2,

and if pushbutton1 has been not pressed and then after i press pushbutton2,it display message 'pb1 is not press' using pushbutton2, in gui)
