This dll calculates real and imaginary parts of eigen values of a real quadrat matrix by use of QR-algorithm.

General plan of using this DLL is as follows:

• register the dll in your system;
• load the size of quadrat matrix;
• load the matrix itself;
• call "Calculate" method;
• call "RealParts" and "ImaginaryParts" methods to get eigen values.

See sample code at the attached project. Please, send any notes about any bugs to mike345@list.ru.
