Hello,
I've made a app which plots a projectile motion and a fixed line at y=2. See figure below.
I wish to mark the intersection point, and show the x-coordinate. Unfortunatly I don't know how.
My question is, how can I mark the intersecting point (and preferably show its x-coordinate)?
I've included the code to make te plot.
greetings,
Ries
function PlotButtonPushed(app, event)
x0 = 0;
y0= app.Y_0EditField.Value;
v=app.VmsEditField.Value;
angle=app.AngledegEditField.Value*(pi./180);
g=9.81;
t= 0:0.0001:3;
x=x0+v*cos(angle)*t;
y=y0+v*sin(angle)*t-(g*t.^2)/2;
if app.holdButton.Value==0
hold(app.UIAxes, 'off')
else
hold(app.UIAxes, 'on')
end
plot(app.UIAxes,x,y)
yline(app.UIAxes,2);
app.UIAxes.XMinorGrid = 'on'
app.UIAxes.YMinorGrid = 'on'
app.UIAxes.XGrid = 'on'
app.UIAxes.YGrid = 'on'
app.UIAxes.XLim = [0 4];
app.UIAxes.YLim = [0 6];
end
