MATRIX CLUSTER for TOWER EIFFEL

copyright:
	developed by: Nicolas Waquier
	you can use/modify it for you own use, but not redistribute it as 
		library/class/cluster; no restriction about executables.
	if you think this cluster must be improved, let me know; I'll do
		it. You can help if you want.

version: 0.1 94/10
state:
	will be expanded.
	report every problem.

contain:
	matrix_of:      an array of numeric elements
	matrix_real:    a mathematical matrix
	matrix_sq:      a square matrix
	matrix4:        a matrix 4x4
	matrix3:        a matrix 3x3
	m_test:         to test the cluster

target use:
	The target use I had in mind while developing was a class of matrix to do spacial transformation of point/line/planes. You create a identity matrix, then rotate, translate it.
	I had to develop it in C for a medical aplication, and wanted the same in eiffel.
	This cluster must be usable with MATRIX [FACTORIAL].
	
future change:
	clean up the classes.
	add the missing features.
	make it interoperate with diferents compilers.
	fine tune to use with factorial

need compiler: Tower Eiffel 1.3.1.0

need clusters: class FORMAT from cluster tower/../sig

time to compile: 13 sec Eiffel -> C
