Change in the matlab table array

hi, i have a sensor having time, acceleration in x, y, z direction. i have imported the data using import command as a column vector. now i want to subtract a certain value from the time vector column so that it starts from zero. i used a stupid method but by using that and runningthe script 3 or 4 times the value in the vector changes to row or some other values. What is the right way to do so?

readtable() would probably be better suited.

Not sure what you're doing since you didn't show your stupid (as you called it, not me) code. I'd use importdata() or csvread() or something like that to get the data in, then to extract the time and have it start from 0, you can do this:

t = data(:, 1);  % Assumes time is in column 1.
% Have the min time be redefined as "0".
t = t - min(t);
