This is Prashanth doing research.as part of my research I choose ADXL 335 accelerometer sensor and took reading around 350 with 0.1s.the response of this sensor in the form of 'g'. so how can convert g value into velocity. if you have Matlab code, please share with me

So you have readings every 0.1s, and the value is in units of g's? And you want to integrate this into velocity?

Share the readings and explain more. What is 'g'? Are these the acceleration values? If yes, you have acceleration and you have time. You know
v = u + gt
Assuming initial velocity = 0
v = gt
Just do this:
v = readings .* time

But the problem with this is that if you take the 3 axis readings in 2d matrix and just keep adding previous velocity to the product of g and t you will get a monotonically increasing function and the lst time I checked while taking the readings I was not going at Mach 2, 10 seconds after taking the readings.
