How can i create a simple working gui that calculates roots using newton-raphson method?

i dont really have a background on programming in matlab, i have created the gui but adding the code was my problem.

Can you please be a bit more specific, exactly what do you need help with?

i have already created the gui but the code doesn't work,, i just researched some codes on google and compiled it,, can you help me with the code?

function [root,numIter] = newton_simple(func,dfunc,tol) % Simple version of Newton-Raphson method if nargin < 5; tol = 1.0e6*eps; end for i=1:30 dx = -feval(func,x)/feval(dfunc,x); x=x+dx; if abs(dx) < tol root = x; numIter = i; return end end root = NaN

function y = equation1(x) %declaring functions A = str2double(get(handles.a,'String')); B = str2double(get(handles.b,'String')); C = str2double(get(handles.c,'String')); y = A*x+B*x+C;

function y = equation2(x) %declare second function z = str2double(get(handles.edit16, 'String')); w = str2double(get(handles.edit17, 'String')); y = w*x+z;

% --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) x = str2double(get(handles.x1,'String')); [root,numIter] = newton_simple(@equation1,@equation2,x,tol); set(handles.iteration,'String',numIter); set(handles.x,'String',root);

can you please help me with the codes?
