MATLAB: Calculate acceleration from velocity and time fron excel

Question

Hi I have an excel sheet with Velocity and Time columns for each step. I need help to input this excel sheet and add a 3rd column with acceleration data.

For example: (Input)

Time (s) Velocity (m/s)

0 50

1 51

2… 52…

For example: (Required Output)

T (s) V (m/s) Acceleration (dV/T)(m/s^2)

0 50 (50-0)/0

1 51 (51-50)/1

2… 52… (52-51)/2

I've used the following to read the Excel

filename='Example.xlsx';

[filepath,name,ext] = fileparts(filename) ;

data = readtable(filename);

N = length(data.t);

Answer 1

acceleration = diff(data.Velocity)./diff(data.Time);

Note that this vector has one entry less than the original ones, so you may be interested in creating a new vector of time at the mid point of each time interval

tt = (data.Time(1:end-1)+data.Time(2:end))/2;
