Version 2.5 of .NET Matri Library has been released and includes the following changes:

Concatenate method has been added to the Matrix and CMatrix objects, allowing fast and efficient horizontal and vertical matrix concatenation.
DeleteRow, InsertRow, DeleteColumn, InsertColumn methods have been added to Matrix and CMatrix objects.
Fixed a bug regarding the overloading of the equality operator of the Vector and CVector objects, causing a NullRefrenceException to be thrown when they were compared with with a null pointer.
Other internal changes and optimizations resulting in improved performance and better memory usage.

The new version of NML gets installed by default in a different directory and can coexist with older versions of the library. Users of previous versions can upgrade to the new version for free.Vesrion 2.5 of NML can be downloaded from here: [url]http://www.bluebit.gr/NET/BNML.zip[/url]

Version 2.2 of .NET Matrix Library

Trifon — Mon, 21 Mar 2005 03:32:42 GMT

Version 2.2 of the .NET Matrix Library has been released.The following list describes the new additions.

SetRow and SetColumn methods have been added to the Matrix and CMatrix classes, allowing to quickly pass values to matrix rows or columns.
Divide method has been added and also Division operator has been defined for the Matrix and CMatrix classes performing right matrix-matrix division, matrix-scalar division and scalar-matrix division.
LDivide method has been added to the Matrix and CMatrix classes performing left matrix division.
Cos, Cosh, Sin, Sinh trigonometric functions have been added to the Complex structure.
IsNaN and IsInfinity methods have been added to the Complex structure.
HasNaNs, HasINFs and IsFinite have been added to the Matrix, CMatrix, Vector, CVector classes allowing to quickly check for NaN and infinity values.
DataPtr property has been added to the Matrix, CMatrix, Vector, CVector classes returning a pointer to the native (unmanaged) memory block where matrix's elements are stored.
Real and Imag methods have been added to the CVector class allowing to split the complex vector to its real and imaginary parts.

Existing users can upgrade their older version for free. Version 2.2 can coexist on the same machine with any other previous version.You may download the new verison of NML from here: http://www.bluebit.gr/NET/BNML.ZIP

Column Covariance and Covariance Matrix

Trifon — Sun, 28 Mar 2004 16:57:43 GMT

Two new methods have been added in version 3.1.2 of MaXC.

ColCovariance method returns the covariance between two matrix columns.

CovarianceMatrix method return a symmetric positive definite matrix with elements set to covariance of current matrix object.

MaXC 3.1 Release

Trifon — Tue, 02 Mar 2004 10:47:17 GMT

Matrix ActiveX Component 3.1 has been released.

Existing users of version 3.0 can have a free update to version 3.1 and use the same Registration Keys with the newer version.

Existing users of version 2.X need to upgrade and receive a new Registration Key.

Matrix ActiveX Component 3.1

Trifon — Mon, 23 Feb 2004 20:42:58 GMT

Version 3.1 of Matrix ActiveX Component to be released in a few days.

MaXC 3.1 introduces new methods that can significantly speed up your programming with matrices.

CorrelationMatrix Method
Advanced & Advanced II editions. The CorrelationMatrix method performs a super fast calculation of the correlation matrix for the data contained in matrix's columns. For a matrix with 40,000 rows and 100 columns, on a 2.4GHz Pentium machine, it takes just one second to execute.

ColCorrelation Method
Advanced & Advanced II editions. The ColCorrelation method returns the correlation coefficient between two columns of the Matrix object.

Norm Method
Advanced & Advanced II editions. The Norm method returns four different types of matrix norms, One norm, Frobenius Euclidean and Infinity norms.

NormalizeColumns, NormalizeRows Methods
Advanced & Advanced II editions. The NormalizeColumns, NormalizeRows methods lets you normalize columns or rows of current matrix in three different ways.

Merge, SubMatrix Methods
All Editions. Merge and SubMatrix methods facilitate data manipulation contained in matrices.

ColSum, RowSum, Trace Methods
All Editions. ColSum and RowSum methods return the column or row sum respectively. Trace calculates the sum of the diagonal elements.
