I/O

In interactive mode, REDUCE normally prints results in a two dimensional ``mathematical'' form, where exponents are raised, quotients are printed with denominator below numerator, and matrices are represented as rectangular blocks. The output can be influenced by a variety of switches, e.g. for reordering or collecting of terms.

For special purposes, additional output forms are available:

linear form: the data can be re-used for later input in REDUCE or another system,
foreign syntax: the expressions are printed in the syntax of FORTRAN, C or another programming language for the direct insertion in numeric codes,
TeX: indirect formatting as input for the TeX layout program to be inserted into a publication.

Examples for q:=(x+y)**3:

natural (default) output:


      3      2          2    3
Q := X  + 3*X *Y + 3*X*Y  + Y

for later re-use:


Q := X**3 + 3*X**2*Y + 3*X*Y**2 + Y**3$

as contribution to a FORTRAN source:


      Q=X**3+3.*X**2*Y+3.*X*Y**2+Y**3

for a LaTeX document:


\begin{displaymath}
q=x^{3}+3 x^{2} y+3 x y^{2}+y^{3}
\end{displaymath}

In addition to direct terminal access, I/O can also be redirected to files.
