matrixes and vectors

[Pietro Terna]

        Hi All,

	I refer to a serie of posts of a few day ago, about the C problem of 
returning a vector.

	To solve the problem in my applications, where I use a lot of matrixes and 
vectors of real numbers, I have introduced two Classes, written in Swarm 
stile (e.g. with createBegin the matrix is generated with malloc etc.).

	I attach here: Matrix.h and Matrix.m, the basic class; Matrix2.h and 
Matrix2.m, inheriting from Matrix and adding some new methods.

	Matrix catches the out of bound run time errors, producing an error 
message with a numerical code used to identify the matrix out of bound.

	These classes containg general methods, plus some methods, maybe, only 
useful for me; for explanations, see the comments in Matrix.h.

	If you create a Matrix2 instance in a probed object, you can right click 
on the Matrix2 label to open a probe to the matrix; going to the methods 
(newly right click on the label of the box) you have the 'print' method, 
which displays the content of the matrix on the current terminal.

        I hope that my classes could be useful.

        Pietro
