Hello,
Let's assume I have the following curves (see smooth solid lines) and I want to discretize them. I know about the discretize function, but what I would want is to discretize them using variable steps (see lines in discretized pattern). I know the easiest way is to manually discretize them by putting all the points hard coded and generating the pattern, but my main question is if there is an automated way through which I could input the reference curve, the number of points and their respective durations and have the curves created automatically.
Many thanks.

x = linspace(0, 400,50);
y = [exp(x/100); sin(x/100)-x/400];
figure
plot(x, y)
grid
figure
stairs(x, y(1,:))
[xb{1}, yb{1}] = stairs(x, y(1,:));
hold on
stairs(x, y(2,:))
[xb{2}, yb{2}] = stairs(x, y(2,:));
hold off
grid
GetData= [xb{1}(1:10) yb{1}(1:10)]
Experiment to get different results.
