Time in While and Intergrator

Hello ,

I have a problem . I want to calculate the time in m / s from While loop so that I can integrate the values. I tried a lot, unfortunately that didn't work. I use the MPU6050 accelerometer . Can you help please, best regards

delete(instrfindall);
clear all
clc
serialPort = 'COM2';                                    

s=serial(serialPort,'BaudRate',9600); 
fopen(s);
%tic 
%t=0.004
m=[];
%t0=0
vec_ax=[0];
vec_ay=[0];
vec_az=[0];
while 1      
  %t_start=datetime('now')
  x = fscanf(s);
  m = str2num(x);
  
  if isempty(m); continue; end
  
  ax = m(1);
  ay = m(2);
  az = m(3);
 
  %t_end=
  %t_delta=
  
  %vec_ax=[vec_ax, ax]
  %vec_ay=[vec_ay, ay];
  %vec_az=[vec_az, az];
  
  %vec_t=[vec_t, t_delta]
  
  %vx = cumtrapz(vec_ax, vec_t)
  %vy = cumtrapz(vec_ay, vec_t)
  %vz = cumtrapz(vec_az, vec_t)
  
  
 
end


fclose(s);

Do you want the system time?

You can take use of clock function or

fprintf('The time is  %s\n', datestr(now,'HH:MM:SS.FFF')).'

Or, if you wish to check the execution time, you can use tic-toc.

thank you i used tic toc
