D.15.6.24 grrndmat
Procedure from library gradedModules.lib (see gradedModules_lib).
- Usage:
- grrndmat(src,dst[,p,b]), intvec src, dst[, int p, b]
- Return:
- matrix of polynomials
- Purpose:
- generate random matrix compatible with src and dst gradings
- Note:
- optional arguments p, b are for 'sparsepoly' (by default: 75%, 30000).
- Todo:
- this is experimental at the moment!
Example:
| | LIB "gradedModules.lib";
ring r=32003,(x,y,z),dp;
print( grrndmat( intvec(0, 1), intvec(1, 2, 3) ) );
==> 6204y, -7833,
==> -12498xz+12773z2, 5664z,
==> -10041x3-11973x2y-5644xy2,-7740xy-5361z2
