| Ausführliche Beschreibung | Newmat library is intended for scientists and engineers
who need to manipulate a variety of types of matrices
using standard matrix operations.
Emphasis is on the kind of operations needed in statistical calculations
such as least squares, linear equation solve and eigenvalues.
.
Newmat supports matrix types: Matrix (rectangular matrix);
UpperTriangularMatrix; LowerTriangularMatrix; DiagonalMatrix;
SymmetricMatrix; BandMatrix; UpperBandMatrix; LowerBandMatrix;
SymmetricBandMatrix; IdentityMatrix;
RowVector; ColumnVector.
.
Only one element type (float or double) is supported (default is double).
.
The library includes the operations *, +, -, *=, +=, -=, Kronecker product,
Schur product, concatenation, inverse, transpose, conversion between types,
submatrix, determinant, Cholesky decomposition, QR triangularisation,
singular value decomposition, eigenvalues of a symmetric matrix, sorting,
fast Fourier and trig. transforms and printing.
