[MTRXCALC is a calculator interface to a rather sophisticated
application performing methods in numerical linear and matrix
algebra. The interface makes many operations very simple and in
general offers convenience-of-use not seen in the software for
professionals. One can solve linear systems, factor matrices,
obtain eigenvalues and etc. at the push of a button.
Alternately one can type their own expressions such as
'A*inv(B*trans(B))' and have it evaluated and displayed. Data
entry is simple also. ]
Long Description:
-----------------
[This application MTRXCALC provides the ease of the calculator interface to both
elementary and sophisticated methods of matrix and linear algebra (complex or real).
Buttons for:
the inverse,determinant,norm and etc.;
solving linear systems via partial or complete pivoting or the QR method;
factoring as LU,Cholesky or QR and then forward or backward substitution;
and eigenvalues,eigenvectors by the Inverse Power or QR sequence;
are quick and convenient.
Typed expressions such as:
'A*inv(B)+trans(C)',
or
'rows( 1,3,5..8)'
are evaluated. and the results are shown in the spread sheet-like display
Elementary row operations can be performed much as on a calculator.
Why so many ways to solve a linear system? Because partly this program is
intended to serve in a tutorial vein making one aware of the various numerical
procedures and of their differing performance. But the hallmark of this
application is CONVENIENCE and EASE of USE.]
