We add the MEX files for Windows in ./bin. If you use Linux or OS/X, you need to download the matlab-json package from the above URL, compile it and install it in ./bin

Functionalities

This package provides the following

• retrieving a series by key: s = get_series_by_key(provider,dataset_code,key). The series is returned in a Matlab structure:
  • s.name: (string) series name
  • s.key: (string) series key
  • s.dimension: (structure) dimensions of the series
  • s.start_date: (structure) starting date
    • s.start_date.year: year
    • s.start_date.sub: number of subperiod ('A' 0, 'Q' 0:3, 'M' 0:11)
    • s.start_date.freq: infra-annual frequency ('A': 1, 'Q': 4, 'M' 12)
  • s.values: ([double]) values

Currently, the package supports only annual, quarterly and monthly data.
