b, z numbers come out but from there onwards e, w, j, k, t and the others leave NaN why?
b=(str2double(get(handles.edit12,'string'))-str2double(get(handles.edit10,'string')))/(str2double(get(handles.edit11,'string'))-str2double(get(handles.edit8,'string')))
z=(str2double(get(handles.edit14,'string'))-str2double(get(handles.edit12,'string')))/(str2double(get(handles.edit13,'string'))-str2double(get(handles.edit11,'string')))
e=(str2double(get(handles.edit16,'string'))-str2double(get(handles.edit14,'string')))/(str2double(get(handles.edit15,'string'))-str2double(get(handles.edit13,'string')))
w=(str2double(get(handles.edit18,'string'))-str2double(get(handles.edit16,'string')))/(str2double(get(handles.edit17,'string'))-str2double(get(handles.edit15,'string')))
j=(str2double(get(handles.edit20,'string'))-str2double(get(handles.edit18,'string')))/(str2double(get(handles.edit19,'string'))-str2double(get(handles.edit17,'string')))
k=(z-b)/(str2double(get(handles.edit13,'string'))-str2double(get(handles.edit18,'string')))
t=(e-z)/(str2double(get(handles.edit15,'string'))-str2double(get(handles.edit11,'string')))
l=(w-e)/(str2double(get(handles.edit17,'string'))-str2double(get(handles.edit13,'string')))
n=(j-w)/(str2double(get(handles.edit19,'string'))-str2double(get(handles.edit15,'string')))
b0=str2double(get(handles.edit10,'string'))
y=b0+b*(x-str2double(get(handles.edit8,'string')))+k*(x-str2double(get(handles.edit8,'string')))*(x-str2double(get(handles.edit11,'string')))

I recommend doing each str2double only once and assign each to a meaningful variable name and then do the calculations. You can examine the variables to see if you got any nan, which is possible if the corresponding string did not represent a scalar double. You can also get nan from 0/0

What you posted does not tell us what is stored in the strings. Show us the result of get() of each of the handles used in the formula
