Matrex is a vectorial spreadsheet. It is better than usual spreadsheets when working with large amounts of data coming from databases, files, or networks. It is strongly multithreaded, expandable, and improves readability. It has adapters to Matlab, Scilab, Octave, and R. License: GNU General Public License (GPL) Changes: The big step forward of this version is the new ISQL module. The ISQL module is a function template to apply SQL queries to vectors in a Matrex project. Other enhancements are the ability to print matrices and presentations, the ability to export matrices and presentations to CSV and XLS, and the ability to import data from a database using an SQL query. Menus were added to remove multiple items, duplicate matrices and functions, and add a function from a matrix (the function will have the matrix as the first argument). A summary step was added for the expression parser. The colors of the windows headers can be changed.
