Post subject: Problem with computing primary decomposition Posted: Fri Aug 29, 2014 9:26 pm 


I'm totally new to SINGULAR. I tried to do the following primary decomposition computation: Code: LIB"matrix.lib"; ring r=0,(x(1..6),y(1..6),z(1..6)),lp; matrix X[3][6]=x(1),x(2),x(3),x(4),x(5),x(6), y(1),y(2),y(3),y(4),y(5),y(6), z(1),z(2),z(3),z(4),z(5),z(6);
intvec m=1,2,3; intvec n=1,5,6; matrix c[3][3]=submat(X,1..3,m); matrix d[3][3]=submat(X,1..3,n);
intvec o=4,3,5; intvec p=2,4,6; matrix e[3][3]=submat(X,1..3,o); matrix f[3][3]=submat(X,1..3,p);
ideal i=det(c),det(d),det(e),det(f);
list A=primdecGTZ(i); but got the following message: Code: > . list A=primdecGTZ(i); ? `string` == `int` failed ? expected `int` == `int` ? expected `string` == `string` ? expected `intvec` == `int` ? error occurred in or before ring.lib::hasFieldCoefficient line 986: ` return (attrib(rng,"ring_cf")==0);` ? leaving ring.lib::hasFieldCoefficient skipping text from ` ` error at token `)` ? leaving primdec.lib::primdecGTZ Does anyone know what's wrong? did I miss some important step in the installation? (I'm running SINGULAR in OSX v. 10.9.4 on 8 GB RAM) Any help is appreciated! Thanks, Camilo.

This is a mismatch of the version of binary and the version of the libraries. You cannot change one without changig the otger (at least not allways)

Thanks for identifying the problem.
Do you (or anyone) know what can I do? That error came out right away while I was trying SINGULAR for the very first time, after I had just installed it from the Singular317ix86Macdarwin.tar.gz and Singular317share.tar.gz (i.e. not having deliberately changed the version of anything).

Probably my fault (not to include the latest changes): load Singular317ix86Macdarwin.tar.gz (it is updated now) again and unpack it at the same place. Should now work.

Thanks so much for the answer.
In the meantime, I installed the bundled Singular4.0.0 version for MacOSX, and now I can do the reported computation with no problems at all.

Hello,
I almost have the same pronlem. I updated my Singular, but still the same. These are my code:
option(prot); LIB"primdec.lib"; ring r=(0,a,b,l,t2),(X,Y,Z,x0,x1,x2,x3),dp; ideal i=X*x0*x1+X*x2*x3Y*x0*x2Y*x1*x3, 4*b*t2^2*x0*x1+2*l*t2^2*x0*x12*l*t2^2*x0*x22*l*t2^2*x1*x32*l*t2^2*x2*x34*l*t2*x0*x1+4*l*t2*x2*x34*b*x0*x1+2*l*x0*x1+2*l*x0*x2+2*l*x1*x32*l*x2*x3, 2*b*t2^2*x0*x2l*t2^2*x0*x1+l*t2^2*x0*x2+l*t2^2*x1*x3+l*t2^2*x2*x3+2*l*t2*x0*x2+2*l*t2*x1*x32*b*x0*x2+l*x0*x1+l*x0*x2+l*x1*x3l*x2*x3; list p=primdecGTZ(i);
Results:
product criterion:58 chain criterion:12 ? `nothing` [ `int` failed ? expected `intvec` [ `int` ? expected `ideal` [ `int` ? expected `map` [ `int` ? expected `module` [ `int` ? expected `string` [ `int` ? expected `list` [ `int` ? expected `poly` [ `int` ? expected `vector` [ `int` ? error occurred in or before primdec.lib::decomp line 3642: ` return(primary);` ? leaving primdec.lib::decomp skipping text from `;` error at token `)` ? leaving primdec.lib::decomp ? leaving primdec.lib::decomp ? leaving primdec.lib::decomp ? leaving primdec.lib::decomp ? leaving primdec.lib::primdecGTZ
I appriciate you help. Thank you,
Calista

Hi Calista, please check and post your Singular version. Please try to update it to 4.0.1 or compile from source https://github.com/Singular/Sourcessee some advices at https://github.com/Singular/Sources/wik ... romsourceJakob Calista wrote: Hello,
