Description: DLL For Numerical calculations

Programming language: PureBasic v4.20 (friendly called PB)
Version 0.0.3.0
by Carlo Somigliana (somic@libero.it)

------------------------------------------------------------------------------------------------------------------
a DLL for numerical calculations (Replaces VBMatr.OCX discontinued) 
 
Implement 40+ Matrix functions, including Determinant, Inverse, Division, Trasposed. 
Solve equation systems, calculate coefficients of polinomial curve, show matrix elements, etc.
Includes equation parser/solver/intergator with variables and functions and other functions

See .pbpt and .bas files for details 

Very fast code. Sample code available in Visual Basic and PureBasic.

Notes:
=======================================================
This DLL uses standard Windows API calling convention
All calls to be declared as Functions, returning an ExitCode (Long or .l), expecially in PB, to avoid Debug problems
Matrices must be passed with a pointer (PB i.e @a()) or first element (VB i.e. a(1,1)) (see examples)
Matrices' elements are all Double (.d = 8 bytes)
Matrices order must be set and correct (i.e. DLL can not ReDim them)
Procedures "aElemOrder" or "Set_aElemOrder" must be always called before any other call to set aElemOrder value inside DLL
This DLL has no run-time error management
Simbol * means a pointer to a variable (Matrix, Long, Double,...)
Simbol @ means memory address of variable/array/etc
When a * is used in the ProcedureDLL declaration, then a @ must be put in front of the relevant parameter
Parameter rc.l always means Squared Matrix (Rows = Col)

Declaration Instructions
========================
* PUREBASIC
-----------
Use IncludeFile "aNuMet.pbpt" (PureBasic ProtoType file) in the PB project file
All calls to be declared as Functions, returning an ExitCode (Long / .l), expecially in PB, to avoid Debug problems

* VISUAL BASIC
--------------
Matrices must be already dimensioned (preferably Option Base 1 - from 1 To n)
Matrices must be passed with first element (see examples)
Arrays (Matrices) must be declared 'As Any' (see samples)
Long values (.l in PureBasic) must be declared 'ByRef'
All calls to be declared as Functions, returning an ExitCode (Long)
Returned values when Double must be declared 'ByRef' and are always the last parameter
