Who is "he"? I have no idea what "read columns on command" means. Who or what is doing the commanding? And where are the columns? Is there some matrix with some columns?
What is Inflation1? Is it a function, script, or data? In line 2, you seem to indicate it's another m-file but you did not include it. Then in line 6 you treat it as if it's a vector of data, not a function.
I'm afraid there is just not enough information for anyone to give an answer.
If still have questions, then attach your data and code to read it in with the paperclip icon after you read this:

To access data from a table use curly braces {} with two subscripts or dot indexing, as in
inflation = diff(Inflation1{:,1}) ./ Inflation1{1:end-1,1} * 100;
or
inflation = diff(Inflation1.inflation) ./ Inflation1.inflation(1:end-1) * 100;
