The same goes for odsopen-ods2oct-oct2ods-odsclose sequences. Mixing read and write operations in any order is permitted (the only exception: not with the JXL -JExcelAPI- interface).

When you're finished, DO NOT FORGET to close the file pointer handle:.

(for writing data) Write the data using = oct2xls (data, ).

Next, optionally split the data in numerical, text and raw data and optionally get the limits of where these came from:.

(for reading data) Read the data using raw_data = xls2oct ( ).

NOTE: the output of these functions is a file pointer handle that you should treat carefully!

First open the spreadsheet file using xlsopen (for Excel or gnumeric files) or odsopen (.ods or.

If you want to move multiple pieces of data to/from a spreadsheet file, the io package offers a much more versatile scheme: There are faster ways, but then you'll have to dive into ActiveX/COM/VisualBasic programming. For each operation, xlsread and xlswrite first have to read the entire spreadsheet file, for write operations xlswrite also has to finally write it out completely to disk. Matlab users are used to xlsread and xlswrite, functions that can only read data from, or write data to, one sheet in a spreadsheet file at a time. Xlswrite / odswrite versus xlsopen / odsopen.

( def my-lab ( cl/open)) will use either MATLAB or Octave, depending on availability Long-term, the "higher-level" API is expected to grow to include getĪnd set operations on all the core datastructures, as well as a "higher level" functions is being developed. Over top of this layer, a set of more sophisticated Set-basic, which operate on flat numeric and string data structures,Īnd eval). Supports only a limited set of operations ( get-basic and The "basic" level is more or lessĪ straight passthrough to the underlying Java libraries, and as such You can interface with whichever *lab is available.Ī lot of work still needs to be done on ferrying more complexĭatatypes to/from Clojure.
