QCMatPack for .Net Key Benefits


QCMatPack is 100% managed code, using only the .Net CF core numeric routines in the matrix and numerical analysis classes. The software makes NO calls to external, non-.Net CF based libraries.


Simple to use, object oriented, matrix and numerical analysis classes for the most common problems in science, engineering, industry, and business.


There are no limits regarding the size of vectors and matrices, other than the amount of free memory on the host computer. There are no limits regarding the size of the vectors and matrices used in the solution of general linear systems, solution of eigenvalue problems, multiple regression, curve fitting and DSP routines.

QCMatPack for .Net Feature Summary

bulletVisual Studio Versions- The software is compatible with Visual Studio 2005,  and higher. It can only be used with .Net CF applications.
bulletComplex number math - implements a complex number class, DComplex, that provides a data structure, functions and operators for manipulating complex numbers. Operator overloading of the +, -, *, /, (etc.) operators make manipulating complex numbers as simple as possible.
bullet.Net based matrix math and linear algebra - The software utilizes several generalized matrix classes, the most important of which are the DDMat for real number matrices and the DXMat class for complex number matrices. These are used for the input and output of data to the numerical analysis routines and the manipulation of real and complex number matrices. The matrix classes are designed so that there is no practical limit, other than the amount of free system memory, to the size of matrices. The DDMat and DXMat are symmetrical, in that the same matrix math and linear algebra routines are available for both real and complex numbers. The matrix classes includes routines for matrix and vector statistics (mean, maximum, minimum, range, sum, variance, standard deviation, sum of squares), matrix norms (1-norm, 2-norm, infinity-norm), utility routines (saxpy, dot product), file I/O, general matrix math functions (addition, subtractions, multiplications, division, transpose, inverse, determinant) and matrix row/column manipulation (insert, delete, copy, and interchange). Operator overloading of the +, -, *, / (etc.) operators make manipulating matrices as simple as possible.



Solutions of Systems of Linear Equations (Real and Complex)

Ax = b

Gauss Jordan, QR Factorization, LU Decomposition, Cholesky Factorization

.Net CF (C# and VB) algorithms (Gauss-Jordan, Cholesky, LU and QR) for solving systems of equations       

Real, solution of equations example       

There is a symmetrical group of eight classes for the solution of real and complex linear systems. These classes correspond to real and complex versions of Cholesky factorization (LESCholesky, LESXCholesky), LU Decomposition (LESLU, LESXLU), QR Factorization (LESQR, LESXQR) and Gauss-Jordan (LESGJ, LESXGJ). Each class provides for the solution of one right hand side, multiple right hand sides and matrix inverse.



Solving for eigenvalues and eigenvectors (Real and Complex)

AX = λX

QL, QR and LR algorithms

.Net CF (C# and VB) algorithms (QL, QR and LR) for the solution of eigenvalues and eigenvectors problems       

Real, solution of eigensystems           

The eigensystem problem is divided into three categories real-symmetric, real-unsymmetric, complex symmetric (Hermitian) and complex unsymmetric. The real-symmetric case is handled using the QL algorithm in class EigenQL. The EigenQR and EigenQR2 classes use the QR algorithm to solve the real-unsymmetric case. And the EigenXLR class uses the LR algorithm to solve general complex eigenvalue problems.



Least Squares Regression

Multiple regression, forward, backward, stepwise and split regression

.Net CF (C# and VB) multiple, forard, backward, stepwise and split regression

Multiple Regression

General multiple regression, forward regression, backward regression, stepwise and split regression and regression summary statistics are found in the MulReg, StepwiseMulReg and SplitMulReg classes.



Curve Fitting

Polynomial, exponential, rational polynomial and cubic splines

.Net CF (C# and VB) curve fitting

Polynomial Curve Fitting

The CurveFit class includes support for polynomial, exponential, rational polynomial, and mixed curve fitting. The CubicSplines class uses a cubic splines algorithm for discrete function evaluation.



Digital Signal Processing

FFTs, Windowing, Power Spectrum

 .Net CF (C# and VB) FFT and power spectrum calculations   

FFT and Power Spectrum Calculation

The DSP class includes routines for real and complex FFT’s and power spectrum calculations. Auxiliary routines calculate FFT magnitudes, phases and frequencies.



Thermocouple Linearization

NIST ITS-90 standard as published in the NIST Monograph 17

The thermocouple linearization routines will convert from millivolts to temperature and temperature to millivolts, for B, E, J, K, N, R, S, T thermocouple types. Calculations are based on the NIST ITS-90 standard as published in the NIST Monograph 175..



Matrix Viewers

.Net (C# and VB) matrix viewer controls for real and complex matrices



DMatrixViewer displays matrix elements of a DDMat (real) matrix

XMatrixViewer displays matrix elements of a DXMat (complex) matrix

The DMatViewer and XMatViewer classes are UserControl subclasses that display real and complex number matrices, respectively. If the matrix is larger than the size you have created the view, scrollbars give the option of scrolling the rows and columns of the matrix.  The matrix viewers include options to change font characteristics, the numeric format of the matrix element values, and the number of displayed rows and columns. The matrix viewer can be read-only, or it can edited by clicking on a matrix element.


bullet100% Managed .Net CF Code - The software is entirely written in C#, resulting in provide better performance and scalability. Managed .Net CF code makes applications easier to deploy and maintain.

Custom Programming Services

bulletQCMatPack is an extremely powerful and flexible software package. It contains over 1000 methods and properties in more than 40 classes. The user manual and  help file documentation are more than 500 pages. This can be overwhelming to the average programmer who wants to start programming today and have the prototype of an application working in a week.
bulletThe variety of user interfaces is as diverse as the industries using the software. The end-user of an application at a mutual fund expects to interact with an application program in a manner different than that of an end-user in health care. The same can be said for other industries: semiconductors, quality control, teaching, biotechnology, etc.
bulletThat is why we have written so many outstanding example programs, pulled from a wide variety of industries using many different styles of user interface.
bulletWe know that your application may be similar to, but still uniquely different from any of our example programs. To that end we offer our programming services to write for you a custom example program that demonstrates how to code and format the user interface you want. That jump start to your project can save you many weeks of work and make you look like a programming genius. All  you have to be able to do is describe in detail what you want the example to do.
bulletUsing QCMatPack for .Net CF, our range of expertise includes Managed C++ (MC++), VB, and C#  programming languages. For more information or a quote, please contact our sales department at sales@quinn-curtis.com
