Hi, how do I change all the values ​​in a specific column ?

ecg = Data(:,6); % Original ECG values

n = 9;                 % Number of bits of the channel  (?)
VCC = 3;               % Operating voltage
Gecg = 1000;           % Sensor gain

ecg_volts = (ecg/(2^n)-1/2)*VCC/Gecg;

and now i want to change the values of the 6 column from ecg to ecg_volts

Data(:,6) = ecg_volts;
