I need help writing a program that makes the ball move along the path.

This is what my codes look likes:

clear all
clc
close all
createWindow(300,600);
obj = drawBall(0,300,5,'y');
x = 0:1:300;
y = 50 * sin(x/(10*pi)) + 100
plot(x,y)
 
for k = 1:x
    xMove(obj,1)
    yMove(obj,ystep)
    redraw
end

Please help me figure out the ystep. I have no idea how to do it. Thanks in advance!

[Walter Roberson]

for k = 1:length(x)-1
    xstep = x(k+1)-x(k);
    xMove(obj, xstep)
    ystep = y(k+1)-y(k);
    yMove(obj, ystep)
    redraw
end

Thank you so much!
