Triplets :: cohMatrix(ZZ,ZZ,Triplet)

cohMatrix(ZZ,ZZ,Triplet) -- cohomology table in matrix form

Synopsis

Description

The hypercohomology table is written in the shifted form with H^i(E(d) in row i and column d+i.
i1 : T = triplet({1,2,3}, {1,3}, {0,2,3})  

o1 = {{1, 2, 3}, {1, 3}, {0, 2, 3}}

o1 : Triplet
i2 : cohMatrix(-7,4,T)

o2 = | 77 50 30 16 7 2 0 0 0 0  0  0  |
