D.4.19.17 writeNmzData
Procedure from library normaliz.lib (see normaliz_lib).
- Usage:
- writeNmzData(intmat M, int mode);
writeNmzData(intmat M, int mode, intmat M2, int mode2, ...);
- Create:
- Creates an input file for Normaliz from the matrix M. The second
parameter sets the mode. How the matrix is interpreted depends on the
mode. See the Normaliz documentation for more information.
It is also possible to give more than one pair of matrix and mode. In
this case all matrices and modes are written. This can be used to
combine modes 4,5,6.
Use mode=20 to specify a grading.
- Note:
- Needs an explicit filename set. The filename is created from the
current filename.
Note that all functions in normaliz.lib write and read their data
automatically to and from the hard disk so that writeNmzData will
hardly ever be used explicitly.
Example:
| LIB "normaliz.lib";
setNmzFilename("VeryInteresting");
intmat sgr[3][3]=1,2,3,4,5,6,7,8,10;
writeNmzData(sgr,1);
int dummy=system("sh","cat VeryInteresting.in");
==> 3
==> 3
==> 1 2 3
==> 4 5 6
==> 7 8 10
==> normalization
==>
intmat Hyperplanes[2][3] = 2,-1,0, // 2x-y >= 0
1, 1,0; // x+y >= 0
intmat Equation[1][3] = 0,1,-1; // y = z
intmat Congruence[1][4] = 1,0,0,3; // x = 0 (3)
writeNmzData(Hyperplanes,4,Equation,5,Congruence,6);
dummy=system("sh","cat VeryInteresting.in");
==> 2
==> 3
==> 2 -1 0
==> 1 1 0
==> inequalities

==> 0 1 -1
