Sure! Here's an example of MATLAB code to generate an S-shaped velocity curve:
```matlab
% Constants
t_total = 10; % Total duration of the curve
v_max = 10; % Maximum velocity
a_max = 2; % Maximum acceleration
% Time vector
t = linspace(0, t_total, 1000);
% Calculate the velocity
v = zeros(size(t));
v(t <= t_total/2) = (2*a_max*t(t <= t_total/2).^2) / (t_total/2);
v(t > t_total/2) = v_max - (2*a_max*(t(t > t_total/2) - t_total/2).^2) / (t_total/2);
% Plot the velocity curve
plot(t, v)
xlabel('Time')
ylabel('Velocity')
title('S-shaped Velocity Curve')
```
This code defines the total duration of the curve `t_total`, maximum velocity `v_max`, and maximum acceleration `a_max`. It then generates a time vector `t` and calculates the velocity `v` at each time point using an S-shaped equation. Finally, it plots the velocity curve.
