% Button pushed function: CalculerButton
function CalculerButtonPushed(app, event)
s = handles.ValeurdeXEditField.String;
try
d = str2double(strsplit(s{:}, ','));
catch
error('Edit field must contain comma separated values such as "6, 5, 3.14"')
end
end
end

function CalculerButtonPushed(app, event)
x=app.ValeurdeXEditField.Value;
try
d = str2double(strsplit(x{:}, ' '));
app.fXEditField.Value=z;
catch
error('Edit field must contain space separated values such as "30 40 50"')
end
i tried this code but i still cant get the values into a vector. my question are probably dumb sorry :((

If you want to get an array of numbers from an EditField, try this:
x = str2num(app.ValeurdeXEditField.Value);
(You don't need to try to parse the array yourself, e.g., by using strsplit. In fact, the lines you have with strsplit will always throw an error when you try to do x{:} or s{:} because x and s are not cell arrays.)
If you want to get a single scalar number from a NumericEditField, try this:
x = app.ValeurdeXEditField.Value;
