I'm really new to MatLab and my programming moduel uses it. My task is to calculate accleration between two cells using the for loop command. this is my code so far but it doesnt work. Please help.

x=ev_data.Time; %time in seconds [Time]

y=ev_data.Speed;

ii=1;

for i=ev_data.Time

y1(ii)=(((ev_data.Speed+1)-ev_data.Speed)/ev_data.Time);

ii=ii+1;

end

figure;

plot(x,y1);

hold on;

plot(x,y)

legend('derivate approximated','sin(x)')

Hi Favour,

I am assuming x and y are vectors(arrays). For each time interval you are calculating acceleration(y11). YOu can follow the below code

x=ev_data.Time;              %time in seconds [Time]
y=ev_data.Speed;
for i=1:ev_data.Time
 y1(i)=(((y(i)+1)-y(i))/x(i));
end
figure;
plot(x,y1);
hold on;
plot(x,y);
legend('derivate approximated','sin(x)') ;
