string - MATLAB Storing a value which is updated continously -

i have matlab gui (by guide) helps me calculations..

i have 'calculate' push button calculates new weight , x value every time click (and manipulate inputs)

i need store 2 value in matrix form dont know how it. needs create matrix equal length of calculate values , store them..

a loop counts number of clicks 'calculate' can not sure.

any appreciated.

here simple code think want. created 'programmatic' gui purpose of demonstration, it's easy implement in guide code. specifically, @ calculatecallback, callback executed when user presses pushbutton used 'calculate'. here there no calculation/data manipulation per se, code takes user inputs text boxes , updates matrix values. there counter keep track of number of calculation.

the code commented si should easy follow. if not please ask clarifications!

function calculategui  clear clc close  %// create figure , uielements handles.fig = figure('position',[440 500 500 150]);  handles.calcbutton = uicontrol('style','pushbutton','position',[60 70 80 40],'string','calculate','callback',@calculatecallback);  handles.val1text = uicontrol('style','text','position',[150 100 60 20],'string','value 1'); handles.val1edit = uicontrol('style','edit','position',[150 70 60 20],'string','');  handles.val2text = uicontrol('style','text','position',[220 100 60 20],'string','value 2'); handles.val2edit = uicontrol('style','edit','position',[220 70 60 20],'string','');  handles.matrixtext = uicontrol('style','text','position',[290 125 100 20],'string','value 1 value 2'); handles.matrixedit = uicontrol('style','text','position',[300 25 80 100]);  handles.countertext1 = uicontrol('style','text','position',[40 20 80 20],'string','loop counter'); handles.countertext2 = uicontrol('style','text','position',[130 20 80 20],'string','');  %// initialize counter # of values calculated handles.calculatecounter = 0; handles.matrixvalues = zeros(1,2);  guidata(handles.fig,handles); %// save handles structure of gui. important      function calculatecallback(~,~)          %// retrieve elements handles structure.         handles = guidata(handles.fig);          %// entries in text boxes. assumes inputs numbers.         val1 = str2double(get(handles.val1edit,'string'));         val2 = str2double(get(handles.val2edit,'string'));          %// if 1st calculation, initialize matrix containing         %// values. otherwise, concatenate current values existing matrix.         if handles.calculatecounter == 0             handles.matrixvalues = [val1,val2];         else             handles.matrixvalues = [handles.matrixvalues; val1,val2];         end         %// print matrix values in text box.         set(handles.matrixedit,'string',num2str(handles.matrixvalues));         %// update counter , display current value in gui.        handles.calculatecounter = handles.calculatecounter + 1;        set(handles.countertext2,'string',num2str(handles.calculatecounter))        guidata(handles.fig,handles); %// save handles structure of gui.     end end 

here screenshot of gui after calculations:

once you're done can fetch data handles.matrixvalues , whatever want them. hope helps started!
