I am currently making a velocity vs time plotting app for an object that is falling with drag. I have worked out the function for it using a bit of calculus and am now trying to plot it. I have plotted it in demos with some values that I preprepared and gotten values od velocity much greater than 1 m/s (which is what I was expecting). However, when I tried to input the same values into my app, to plot them, on my plot the values never exceeded 1. This made me think that MATLAB is somehow scaling my y axis to make all the values plot relative to 1 (which is seemingly the equivalent of the terminal velocity). I tried using,

ylim([0 n]);

to fix this, but that didnt change anything. Here is my code:

function startupFcn(app)
            app.MaxMassEditField.Value = 100;
            app.AreaEditField.Value = 1;
            app.DragCoefficientEditField.Value = 1;
            app.gEditField.Value = 1;
            app.MediumDensitryEditField.Value = 1;
            app.MassSlider.Limits = [10^(-7), app.MaxMassEditField.Value];

            Area = app.AreaEditField.Value;
            Cd = app.DragCoefficientEditField.Value;
            g = app.gEditField.Value;
            density = app.MediumDensitryEditField.Value;
            mass = app.MassSlider.Value;


            
            time = linspace(0, 100, 10000);
            exponent = exp(2*sqrt((g*Area*density*Cd)/(2*mass))*time);
            coefficeint = -sqrt((2*mass*g)/(density*Area*Cd));
            velocity = coefficeint * (1-exponent)./(1+exponent);
            plot(app.UIAxes, time, velocity)
            ylim([0 100]);
        end

(^for startup function)

Area = app.AreaEditField.Value;
            Cd = app.DragCoefficientEditField.Value;
            g = app.gEditField.Value;
            density = app.MediumDensitryEditField.Value;
            mass = app.MassSlider.Value;

            app.MassSlider.Limits = [10^(-7), app.MaxMassEditField.Value];

            
            time = linspace(0, 100, 1000);
            exponent = exp(2*sqrt((g*Area*density*Cd)/(2*mass))*time);
            velocity = - (1-exponent)./(1+exponent);
            plot(app.UIAxes, time, velocity);
            ylim([0 8]);

(^for every time the “plot” button is pressed)

I am super lost right now. Thank you in advance for your help.
