I have to input a function where the output is reliant on the y-axis coordinate
Uwind = -75*(1-((75-y)/75)^2)
Is there any way that i can make the y value the y coordinate at any given point along the x axis?

syms y
Uwind = -75*(1-((75-y)/75)^2)
fplot(Uwind)
is this what you are looking for ? if not let know

It doesn't seem like its changing anything. When I add it into the vx components it doesn't alter the final plot

can you show the code?

ax=-(D/m)*(vx*vx+vy*vy)^0.5*vx;
ay=-g-(D/m)*(vx*vx+vy*vy)^0.5*vy;
vx=Uwind+vx+ax*dt;
vy=vy+ay*dt;
x(i+1)=x(i)+vx*dt+.5*ax*dt^2;
y(i+1)=y(i)+vy*dt+.5*ay*dt^2;
t(i+1)=t(i)+dt;
i=i+1;
