![]() To keep ascending compatibility, old function epxbd2exc can however still be used.įunction impexc2bd, that imports data csv files into Scilab, has been improved.Īs for most other econometric function, Grocer now has contains a adf1 function, that makes Augmented Dickey Fuller tests, as function adf, but that works only with matrices.įunction tsmat2ts that transforms series in a tsmat into ts has been extended to allow the addition of a prefix to the names of the corresponding ts. Lastly function epxbd2exc has been renamed for more clarity epxbd2csv since it exported data in a text format. Note also that function readxls is more efficient than the readxlsx one, so you should prefer the former in your work. Note however that all these functions can be used only with Scilab versions starting from 6.0. Grocer also incorporates functions xlinfo, xlread and xlwrite from this toolbox. All this progress comes from the incorporation into Grocer of Stéphane Mottelet's toolbox xlreadwrite. Function readxls2bd has consequently been adapted and can now also read these recent Excel files. The main innovation of this version is the addition of a function readxlsx, that can read xlsx Excel files and of a function expb2xls that can export data to Excel files. (1): Grocer version 1.84 has been posted on the web.
