You need to give the equations and then people would help you

@Ls. Below is a screenshot of your question I just took. Where exactly on that do you show the equation? Because we're not seeing it.

Do YOU see any formulas or equations above? Because I sure don't.

Not sure if you have given the correct equations:

% Specify n, t and x
n = 10;
t = (1:n)';  x = randn(n, 1);       % generate some data
% Initialize vx and ax
vx = zeros(n, 1);
ax = zeros(n, 1);
% vx(1) and ax(1)
vx(1)=(x(1)-x(n-1))/(t(n)-t(n-1));   % check your equations
ax(1)=(vx(1)-vx(n-1))/(t(n)-t(n-1));  % check your equations
for i=2:n
    vx(i)=(x(i)-x(i-1))/(t(i)-t(i-1));
    ax(i)=(vx(i)-vx(i-1))/(t(i)-t(i-1));
end
