reactantMatrix -- Computes the reactants matrix of a Reaction Network.

Synopsis

• Usage:

  RM = reactantMatrix N

• Inputs:
  • N, an instance of the type ReactionNetwork, a chemical reaction network.
• Outputs:
  • RM, a matrix, whose rows encode the educt complexes of N.

Description

i1 : N = reactionNetwork "A + 2B <--> 3A + 4B"

o1 = A+2B-->3A+4B
     3A+4B-->A+2B

o1 : ReactionNetwork

i2 : RM = reactantMatrix N

o2 = | 1 2 |
     | 3 4 |

o2 : Matrix ZZ  <-- ZZ

i3 : N = oneSiteModificationA()

o3 = S_0+E-->X
     X-->S_0+E
     X-->E+S_1
     S_1+F-->Y
     Y-->S_1+F
     Y-->S_0+F

o3 : ReactionNetwork

i4 : RM = reactantMatrix N
