% Callbacks that handle component events

% Button pushed function: calculateButton
function calculateButtonPushed(app, event)
p = app.Densitykgm3EditField.Value;
V = app.VelocitymsEditField.Value;
D = app.DiametermEditField.Value;
u = app.dynamicviscosityNsm2EditField.Value;
%reynolds number function
Re = (p*V*D)/u;
app.ReresultEditField = Re;
end

Set the component property this way
app.ReresultEditField.Value = Re;
