Exchange
matrices between DERIVEâ and EXCELâ |
||||
|
|
The file DERIVE.XLA is a Excel-addin-macro that contains function to
transfer vectors and matrices from DERIVE
to Excel 95/97/2000/XP and vice versa. It is useful, for example, to
make well refined reports and graphs, or to test algorithms in different environments.
It works like the standard copy/paste functions. Very easy to use. Freeware.
Tested with DFW 4.xx (all versions) and 5.0. For further details see Exporting
DERIVE into Excel |

EULER is a very nice freeware program for quick and interactive computations
with vectors and matrices, real and complex numbers. In general, EULER is a
numerical matrix system. (EULER is not a MatLab clone, but very similar to
this program). Many times we need to compare matrix results in different
environment. This little addin allows the exchange matrices between Euler and
Excel . For further details see Addin for exchanging matrices between EXCEL and

Developed at INRIA, Scilab is suitable for system control and signal processing
applications.It is freely distributed in source code format (see the
copyright file).Scilab is made of three distinct parts: an interpreter,
libraries of functions (Scilab procedures) and libraries of Fortran and C
routines. Scilab is a very nice freeware program for quick and interactive
computations with vectors and matrices, real and complex numbers. For further
details see Exchange matrices between Scilab
