PRESENTATION
------------
Matrices is a simple program with a nice GUI which makes some simple 
operations on matrices, as: product rows x columns, simple or full matrix 
reduction, computation of the determinant and computation of the inverse 
matrix for a square matrix.
It has 24 memories to store matrices (each one the alfabet letters). Letters 
I and Q have special meaning: the I is the unitary matrix. When you specify 
to use the I, you must insert its dimensions , but not its content. The Q 
(for Quotient) is reserved for future use.
The program has 5 gadgets to select the operations and 24 buttons to view 
and to edit the memories.
The menus are 2: Project and Matrix.
Project has the items New, Load, Save, Save As which let you to clear, to 
load or to save all the memories. There is also About and Quit.
Matrix has the items Copy and Move to copy/move a matrix in a memory (with 
move the source memory is cleared), Insert and Delete to insert a new matrix 
or to delete an existing one; again, Read and Write to read/write a single 
matrix in ASCII format from/to a file.
The ASCII format is the following:
first row: <letter>(<x>x<y>)
other rows: <item1> <tab> <item2> <tab> ... <tab> <itemN>

For example:
A(2x3)
3	4	-1
6	10	5
When you start an operation, a requester appears asking for the source 
matrix (or the 2 source matrices for the product) and the destination 
matrix. If the memories specified are empty, a requester appears for each 
empty memory asking forthe sizes of the matrix, and then another asking for 
the contents; if the matrices are full, the old contents will be used.
