Module Name: pkgsrc Committed By: asau Date: Wed Aug 11 20:06:25 UTC 2010 Modified Files: pkgsrc/math/newmat: Makefile PLIST distinfo Log Message: Update to Newmat11 Contributed by Kamel Derouiche via PR pkg/43741 Changes in this version: It works with Borland Builder version 6, 8; Microsoft Visual C++ 6,7,8; Open Watcom 1.7a; Gnu version 3, 4 and Intel for Windows & Linux compilers 9, 10. Options and work-arounds for older compilers are being removed. You can enter values from an integer array with statements like Matrix A(3,2); int a[] = { 11,12,21,22,31,33 }; A << a; There is a new matrix type SquareMatrix. You can use this where you know a matrix is square. The only place where the information that a matrix is used is in the Kronecker product KP(A,B). If A is band and B is any square matrix type (i.e. type SquareMatrix or band, triangular, symmetric or diagonal) the result is band. If B is type Matrix then the result is of type Matrix. Apart from this it may be worth using the SquareMatrix type to improve readability of a program and to make sure that a matrix that is intended to be square really is square. There is a new routine for carrying out cross products of ColumnVectors or RowVectors of length 3 and new routines for updating a triangular matrix derived from a Cholesky decomposition. Interfacing with old C functions involving one and two dimensional arrays is simplified. Additional QR functions, extend_orthogonal function. Lower-case versions of functions. You can use the manipulators scientific and fixed in the matrix output expressions.
