@hackage bed-and-breakfast0.3.1

Efficient Matrix operations in 100% Haskell.

v0.1

Initial version, features det, basic arithmetic operations, and instances for Float, Double, Complex, and Rational.

v0.1.1

Fixed wrong algorithm for computing the inverse of a Matrix.

v0.1.2

Added instances for Num Matrix, Fractional Matrix, and Eq Matrix.

v0.1.3

inv is now a total function and will no longer call error if a matrix is not invertible. Also Matrix derives Data.Typeable now.

v0.1.4

Added scale, and methods for joining matrices vertically and horizontally. Corrected a bug in isUnit reported by Charles Durham. isUnit returned True for any matrix for which all (== 1) . trace would have, which is wrong).

v0.2

A little bit more documentation. Also moved some functions (isXXX) away from the type class MatrixElement. Properly flagged the package as experimental (was improperly marked as stable, copied form a template).

v0.2.1

Added cofactors, adjugate, minor, and minorMatrix.

v0.2.2

rank works now for any Matrix component type.

v0.2.3

Added Read instance for Matrix. Improved on documentation.

v0.3

Added a QuickCheck test suite, fixed a bug in det (det would crash for singular matrices, where it should return 0; it does so no).

v0.3.1

Added TemplateHaskell syntactic sugar (see Numeric.Matrix.Sugar). Rewrote multiplication. matrix function build an array faster now.
