Im runnin my App Designer and I got error by error, the last i got i didn't know what to do, hope u guys can help me please.
yinitial = 0.01;
yn(1) = yinitial;
dyn(1) = 1e-2;
while (abs(dyn(in))>1e-4)
An(in) = app.b.Value*yn(in)+app.z.Value*(yn(in))^2;
Tn(in) = app.b.Value+2*app.z.Value*yn(in);
Pn(in) = app.b.Value+2*(app.z.Value^2+1)^(0.50)*yn(in);
Rn(in) = An(in)/Pn(in);
Dn(in) = An(in)/(app.b.Value+2*app.z.Value*yn(in));
fn(in) = -app.Q.Value*sqrt(app.S.Value)*An(in)*Rn(in)^(2/3)*app.n.Value^(-1);
ffn(in) = (sqrt(app.S.Value)*app.n.Value^(-1))*((Rn(in)^(2/3)*Tn(in))+(Tn(in)/Pn(in))-((2*yn(in)*Rn(in))/Pn(in)));
yn(in+1) = yn(in)-fn(in)/ffn(in);
dyn(in+1) = -fn(in)/ffn(in);
Areah = (app.b.Value+(app.z.Value*Calado_Normal))*Calado_Normal;
Vel = app.Q.Value/Areah;
T = app.b.Value+(2*app.z.Value*Calado_Normal);
F = Vel/((9.81*(Areah/T))^0.5);
Alt = round(Calado_Normal,1)+0.3;
app.V.Value = Vel;
app.CN.Value = Calado_Normal;
app.FR.Value = F;
app.A.Value = Alt;
app.AH.Value = Areah;
app.E.Value = T;
Error is in line 'Vel'

The error says,
app.V.Value = Vel
The value the component 'V' in the App Designer expects a double scalar value and also expects the value to be within the range of the limits. So, the value it is being assigned is not within the limits.
Numeric components in the App Designer have range limits specified. So the value it expects should lie with in the limits. To change the limits, you may click on the component in the design view and you can find the Limits in the value section. Programmatically, you can change it using the app.V.Limits=[lower,upper]
Refer limits to know more about the Limits of the Numeric edit field in App Designer
