From: info@mathtools.com Date: Sat, 01 Feb 1997 23:50:12 -0200 To: wpower@spock.physik.uni-konstanz.de Dear Sir or Madam, We are pleased to send you the latest news digest from MathTools, regarding news and updates about our products. If you need more information, just hit the 'Reply' button and ask. Sincerely, The MathTools. Contents =3D=3D=3D=3D=3D=3D=3D=3D * Matlab 5 and MATCOM / MAT<LIB> upgrade policy * (NEW PRODUCT) MathTools Accelerator for Visual C++ * EasyMex: MEX files made easy for PC/Windows users * No Support for Borland C++ 4.0x * Current list of Technical Documents Matlab 5 MATCOM / MAT<LIB> upgrade policy =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D A Matlab 5 compatible version of our products is under intensive development, and will be available later this year. Our prices for the new version have not been set yet, however, all MATCOM V2 customers will get a free upgrade to the Matlab 5 compatible version. MathTools Accelerator for Visual C++ =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D The MathTools Accelerator provides significant performance gains for MATCOM and MAT<LIB> programs using Linear Algebra and matrix multiplication. Those operations are accelerated using Pentium and Pentium-Pro optimized assembler routines, and the Visual C++ compiler (2.0 or later). Examples for performance gains for a 120Mhz Pentium: Matrix size n=3D100 n=3D200 ------------------------------ Multiplication x1.83 x2.60 Matrix inverse x1.11 x1.12 QR factoring x1.42 x1.25 Requirements o MATCOM or MAT<LIB> o Visual C++ 2.0 or later o Windows 95/NT o Pentium 120 or better Visit http://www.mathtools.com/matacc.html for more details. EasyMex: MEX files made easy for PC/Windows users =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D An EasyMex solution is available for PC users. This solution creates MEX files without using cmex.bat or depending on the WATCOM C++ compiler. This is accessible to all users as TechDoc #1028 (http://www.mathtools.com/techdocs/td1028.html). If you were having trouble using MEX files on Windows NT, try EasyMex. (When using EasyMex, be sure to change directory in Matlab to the mex directory before running it. Do not run it from the path; this might cause GPF.) Note: This is for Windows 95 / Windows NT only. No Support for Borland C++ 4.0x =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Our products will only work with Borland C++ 4.5 or later. Versions 4.0x are not supported.
