Tengo 2 gráficas , en el eje Y tengo Aceleración en gráf. 1 y Velocidad en gráf. 2. Y en el eje X para ambas tengo Periodo (Segundos). ¿Como puedo crear una tercera gráfica?

La tercera grafica debe tener en Y el valor de la aceleración y en el eje X debe tener el valor de desplazamiento. Muchas gracias de antemano por su ayuda

Hi Queren,

It is my understanding that you want to plot acceleration vs displacement, given acceleration vs time and velocity vs time.

To plot acceleration versus displacement, you need to integrate the velocity data over time to calculate displacement. For discrete data, numerical integration, such as "cumtrapz" (Cumulative trapezoidal numerical integration), can be used for this purpose.

Below is a sample MATLAB code snippet demonstrating how to achieve this:

time = linspace(0, 10, 100); % 0 to 10 seconds
velocity = sin(time); % Example velocity data
acceleration = cos(time); % Example acceleration data
displacement = cumtrapz(time, velocity);%cumulative trapezoidal integration
figure;
plot(displacement, acceleration);
xlabel('Displacement');
ylabel('Acceleration');
title('Acceleration vs. Displacement');
grid on;

Refer to the following MATLAB documentation for more information on "cumtrapz":
