Is it possible to extract a set of data from an equation and store it in a uitable?

I want to extract the output data from an equation to a uitable and then later on export it to excel. Not sure if the first part is possible.

My code that I'm trying to extract data:

C_0 = str2double(get(handles.Input_C_0,'String'));
v = str2double(get(handles.Input_v,'String'));
t = str2double(get(handles.Input_t,'String'));
D = str2double(get(handles.Input_D,'String'));
R = str2double(get(handles.Input_R,'String'));
t_half = str2double(get(handles.Input_t_half,'String'));
X1 = str2double(get(handles.Input_X1,'String'));
X2 = str2double(get(handles.Input_X2,'String')); %%%all user inputs
x = X1:0.1:X2;    
lambda = (0.69314718)./t_half;
beta = sqrt((v./(2.*D)).^2+(lambda.*R)./D); 
subA = (x-t.*sqrt((v./R).^2+(4.*lambda.*D)./R))./2.*sqrt((D.*t)./R);
subB = (x+t.*sqrt((v./R).^2+(4.*lambda.*D)./R))./2.*sqrt((D.*t)./R);
C1 = (1./2).*exp((v.*x)./(2.*D)).*(exp(-beta.*x).*erfc(subA)+exp(beta.*x).*erfc(subB)); %%%equation with sub equations
C = C1./C_0; 
plot(x,(C));

C will generate a graph with values for each x, I wonder if I can put it in a uitable

Which equation. Please post an example in formatted code.

Hey thanx for the reply!

I tried adding it to my code for another button, but somehow it isn't working...

---------------------------

guidata(hObject, handles);

handles.output = hObject;

C_0 = str2double(get(handles.Input_C_0,'String'));

v = str2double(get(handles.Input_v,'String'));

t = str2double(get(handles.Input_t,'String'));

D = str2double(get(handles.Input_D,'String'));

R = str2double(get(handles.Input_R,'String'));

t_half = str2double(get(handles.Input_t_half,'String'));

X1 = str2double(get(handles.Input_X1,'String'));

X2 = str2double(get(handles.Input_X2,'String'));

x = X1:0.1:X2;

lambda = (0.69314718)./t_half;

beta = sqrt((v./(2.*D)).^2+(lambda.*R)./D);

subA = (x-t.*sqrt((v./R).^2+(4.*lambda.*D)./R))./2.*sqrt((D.*t)./R);

subB = (x+t.*sqrt((v./R).^2+(4.*lambda.*D)./R))./2.*sqrt((D.*t)./R);

C1 = (1./2).*exp((v.*x)./(2.*D)).*(exp(-beta.*x).*erfc(subA)+exp(beta.*x).*erfc(subB)); %%% equation with sub equations

C = C1./C_0;

data = num2cell([x(:),C(:)]);

set(DATA_TABLE, 'Data', data); %%% uitable is tagged DATA_TABLE

--------------------------------

If the uitable is tagged DATA_TABLE, then

UiTableHandle = findobj(0,'Tag','DATA_TABLE');

set(UiTableHandle,,'Data', data);

Sweet, it works and the Excel is in the Matlab directory, thanx for the help.
