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

Synopsis

• Function: cohMatrix

• Usage:

  cohMatrix(lo,hi,T)

• Inputs:
  • lo, an integer, the leftmost degree of the table
  • hi, an integer, the rightmost degree of the table
  • T, an instance of the type Triplet, a homology triplet
• Outputs:
  • a mutable matrix, a hypercohomology table in matrix form

Description

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  |
