Hi everyone,
I want to take the results from vx and then apply them to the find ax, but the matrix are different sizes so I am reciving an error. Is the a away to rectify this so i can use the reulting vx matric for the ax eqaution? I cannot figure out how to match the size.
Here is the code I am working with.
% x values of particle 1
x = [2.1547 2.1104 2.0498 1.9743 1.8852 1.7843];
% t values of particle 1
t = [0.1346 0.2015 0.2682 0.3345 0.4006 0.4665];
% difference
dx = diff(x);
dt = diff(t);
% vx - velocity in x direction
vx = dx./dt;
% ax - acceleration in x direction
ax = vx./dt;

There is no error... If you are finding the difference, have a look on gradient.
