Follow new rules for<I>for (int i; ... )</I> construct.Change Boolean, TRUE, FALSE to bool, true, false. Change ReDimensionto ReSize. SubMatrix allowszero rows and columns. Scalar <TT>+</TT>, <TT>-</TT> or <TT>*</TT>matrix is OK. Simplifysimulated exceptions. Fix non-linear programs for AT&Tcompilers. Dummy inequality operators. Improve internal row/column operations.Improve matrix LU decomposition. Improve sort. Reverse function. IsSingularfunction. Fast trig transforms. Namespace definitions.<P><B>Newmat08A - July, 1995:</B><P>Fix error in SVD.<P><B>Newmat08 - January, 1995:</B><P>Corrections to improve compatibility with Gnu, Watcom. Concatenation ofmatrices. Elementwise products. Option to use compilers supporting exceptions.Correction to exception module to allow global declarations of matrices. Fixproblem with inverse of symmetric matrices. Fix divide-by-zero problem in SVD.Include new QR routines. Sum function. Non-linear optimisation.GenericMatrices.<P><B>Newmat07 - January, 1993</B><P>Minor corrections to improve compatibility with Zortech, Microsoft andGnu. Correction to exception module. Additional FFT functions. Someminor increases in efficiency. Submatrices can now be used on RHS of =.Option for allowing C type subscripts. Method for loading short lists ofnumbers.<P><B>Newmat06 - December 1992:</B><P>Added band matrices; 'real' changed to 'Real' (to avoid potentialconflict in complex class); Inject doesn't check for no loss ofinformation; fixes for AT&T C++ version 3.0; real(A) becomesA.AsScalar(); CopyToMatrix becomes AsMatrix, etc; .c() is no longerrequired (to be deleted in next version); option for version 2.1 orlater. Suffix for include files changed to .h; BOOL changed to Boolean(BOOL doesn't work in g++ v 2.0); modifications to allow for compilersthat destroy temporaries very quickly; (Gnu users - see the section ofcompiler performance). Added CleanUp, LinearEquationSolver, primitiveversion of exceptions.<P><B>Newmat05 - June 1992:</B><P>For private release only <P><B>Newmat04 - December 1991:</B><P>Fix problem with G++1.40, some extra documentation<P><B>Newmat03 - November 1991:</B><P>Col and Cols become Column and Columns. Added Sort, SVD, Jacobi,Eigenvalues, FFT, real conversion of 1x1 matrix, <I>Numerical Recipes inC</I> interface, output operations, various scalar functions. Improvedreturn from functions. Reorganised setting options in "include.hxx".<P><B>Newmat02 - July 1991:</B><P>Version with matrix row/column operations and numerous additionalfunctions.<P><B>Matrix - October 1990:</B><P>Early version of package.<P><A HREF="sources.html"> next</A> - <A HREF="sources.html"> skip</A> - <A HREF="intro.html"> up</A> - <A HREF="index.html"> start</A><P></BODY></HTML>?? 快捷鍵說明
