How to multiply two columns of the same table?
137 views (last 30 days)
Hello, I have a set of data with two columns: "Item_price" (column 5) , "Item_cnt_day" (column 6)
I want to multiply these to columns in order to get a new column "revenue":
When I use the operator ".*", I only get the debug result that the operator doesn't work for tables.
This is the codeline I got right now:
df_train.revenue = df_train(:,5).*df_train(:,6)
