Matrex 1.2 released

Finally Matrex 1.2 has been released!

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.
It is therefore possible:

• to apply filters on parts of the vectors
• to order the elements of the vectors
  
• to aggregate them

all with simple SQL queries. The internalsql document contained in the distributions explains how.
As far as I know, no other spreadsheet application allows something similar.

Other enhancements are:

• Print matrices and presentations.
• Export matrices and presentations to csv and xls.
  
  
  
  
• Import data from database, using an SQL query.
• Menus to remove multiple items, duplicate matrices and functions, add function from a matrix (the function will have the matrix as first argument).
  
  
  
• A summary step for the expression parser.
  
  
• Possibility to change the colors of the windows headers.
  
  
  

Also, several bugs have been removed (dates formatting, items renaming, boolean matrices editing).
