letterds = datastore("*_M_*.txt");
data = read(letterds);
data = scale(data);
plot(data.X,data.Y)
axis equal
plot(data.Time,data.Y)
ylabel("Vertical position")
xlabel("Time")
function data = scale(data)
data.Time = (data.Time - data.Time(1))/1000;
data.X = 1.5*data.X;
end

It keeps coming up with an error message when I enter that code into task 2, is there an alternative code?

I echo the same question. It keeps saying " does the variable preprocds exist?"

What is the link for the on-ramp course. If I call it up can I jump to that question or do I have to do all the prior tasks before getting to that?

function data = scale(data)
data.Time = (data.Time - data.Time(1))/1000;
data.X = 1.5*data.X;
data.X = data.X - mean(data.X);
data.Y = data.Y - mean(data.Y);
end
