Hi I was hoping someone can help me with my code, I'm new to matlab
data=csvread('TP4765.csv')% Import data
N=size(data,1);% determine number of increment
m=0.001;
%%%%%%%%%%%%%%%%%
the csv is 2052766x7 matrix
I would like like to replace the first colum with a vector starting from 0 in increment "m" for N times(increase 0.001 increment 2052766 times)
Thanks
Thuan
