Concatenate financial time series objects horizontally




horzcat implements horizontal concatenation of financial time series objects. horzcat essentially merges the data columns of the financial time series objects. The time series objects must contain the exact same dates and times.

When multiple instances of a data series name occur, concatenation adds a suffix to the current names of the data series. The suffix has the format _objectname<n>, where n is a number indicating the position of the time series, from left to right, in the concatenation command. The n part of the suffix appears only when there is more than one instance of a particular data series name.

The description fields are concatenated as well. They are separated by two forward slashes (//).


Construct three financial time series, each containing a data series named DataSeries:

firstfts  = fints((today:today+4)', (1:5)','DataSeries','d');
secondfts = fints((today:today+4)', (11:15)','DataSeries','d');
thirdfts  = fints((today:today+4)', (21:25)','DataSeries','d');

Concatenate the time series horizontally into a new financial time series newfts:

newfts  = [firstfts secondfts thirdfts secondfts];

The resulting object newfts has data series names DataSeries_firstfts, DataSeries_secondfts2, DataSeries_thirdfts, and DataSeries_secondfts4.

Verify this with the command

ans = 

Use chfield to change the data series names.


If all input objects have the same frequency, the new object has that frequency as well. However, if one of the objects concatenated has a different frequency from the others, the frequency indicator of the resulting object is set to Unknown (0).
