print polynomial with *'s for multiplications
StarPrint(F: RINGELEM)
StarPrintFold(F: RINGELEM, LineWidth: INT)
StarSprint(F: RINGELEM): STRING
StarSprintFold(F: RINGELEM, LineWidth: INT): STRING |
These functions print the polynomial F with asterisks added to denote
multiplications. They may be useful when transfering polynomials or
rational functions from CoCoA to other mathematical software (e.g. Gap,
Maple, Macaulay, Singular,..).
StarPrint
inserts newline
characters (only between terms) with the aim of avoiding lines longer
than 70 characters; the second argument to
StarPrintFold
is for
specifying a different width limit; a non positive value is treated as
meaning no limit. The
StarSprint
functions print the value into
a string.
Use R ::= QQ[x,y];
F := x^3+2xy-y^2;
StarPrint(F);
1*x^3 +2*x*y -1*y^2
-------------------------------
StarPrintFold(F,1); -- this will print one term per line
1*x^3
+2*x*y
-1*y^2
-------------------------------
D := OpenOFile("example");
Print StarSprint(F) On D; -- this will print F into the file "example"
Close(D);
-------------------------------
