I imported a csv file into Mathematica and I want to append columns to it:
Append[Data[[i]], Cycle[i][[15, j]]], {i, 1, Length[CycleStartTime]}];
This allows me to append one column, what if I want to append more columns?
You may use Join:
Join
In[1]:= Join[{{a, b}, {c, d}}, {{1, 2}, {3, 4}}, 2] Out[1]= {{a, b, 1, 2}, {c, d, 3, 4}}
