i have table with 2 columns , the input are functions and Time intervals , in which each function must be plotted .

i want to create a variable , that is equal to the end value of the before last function . for example the function f1 ended at the time t_end , this variable should be m=f1(t_end) . in order to be able to use it in the body of the next function ( f2= f1(t_end)+...) if i want .

the problem ist how to get this variable as an input argument , the whole code look like that

 MTablecurrentdata=get(handles.Mtable,'data');
 Momentdata=MTablecurrentdata(:,1); 
 Timedata=MTablecurrentdata(:,2); 
 if size(MTablecurrentdata,1)==1
    Mi= str2func(['@(t)' Momentdata{1,1}]);
    Ti = str2num(Timedata{1,1});
    fplot(Mi,Ti,'Parent',handles.axes1);
 else 
    for i=2:size(MTablecurrentdata,1)        
        Told = str2num(Timedata{i-1,1});  %old time interval 
        Tnew = str2num(Timedata{i,1});   %new time interval 
        %t2 end time of the old function [t1 t2]
        Endtime=max(str2num(Timedata{i-1,1})); 
        %t3 start time of the new function [t3 t4]    
        Starttime=min(str2num(Timedata{i,1})); 
        Mfuncold= str2func(['@(t)' Momentdata{i-1,1}]);
        Mfuncnew= str2func(['@(t)' Momentdata{i,1}]);
        fplot(Mfuncold,Told,'Parent',handles.axes1);
        hold(handles.axes1,'on')
        fplot(Mfuncnew,Tnew,'Parent',handles.axes1);
        hold(handles.axes1,'on')
    end
    hold(handles.axes1, 'off')
 end
