Hi, I have 4 lists
1st ,2nd and 3rd -> composed by column : Date and Value (some date missing)
4th --> a coloumn of the complete list of date
I'd like to obtain a matrix made by the column : Date (complete, from 4th) , Value1, Value2, Value3. Each value mast be associated correctly to it's date. When a value for a date is absent , write NaN.
How can I do ? thanks for your answer.
