Hello,
I read datas from a excel file: x-column is "time" and y-column is "velocity" and plot them. Everything is ok.
e.g. Start:
0s 0prm
20s 200rpm
40s 250rpm
80s 300prm
......
Now I would like to give my motor control the new velocity after the time is over depends on my table data. Maybe you know an advice how I can do it? Thanks a lot
t = readtable("Daten.xlsx","Sheet",2);
x = table2array(t(:,1));
y = table2array(t(:,3));
stairs(app.UIAxes,x,y,'-o');

@Chris are you asking how to add data to the table or how to extrapolate a velocity estimate given a future time?
If your goal is to do the latter, you'll need to provide more info about how you expect the velocity to change. For example, if you expect a simple logrithmic growth (for demo purposes only),
x = [0 20 40 80];
y = [0 200 250 300];
clf()
hold on
grid on
plot(x,y,'b-o','DisplayName','RawData')
z = lsqcurvefit(@(p,xdata)p(1)+p(2).*log(xdata),[0,1],x(2:end)',y(2:end)');
newX = 5:100;
newY = z(1)+z(2).*log(newX);
plot(newX, newY, 'k--','DisplayName','Fit')
legend('Location','SouthEast')
