logarithmicForm(...,Projective=>...) -- a boolean option to produce a projective logarithmic form

Synopsis

• Usage:

  logarithmicForm(..., Projective => b)

• Inputs:
  • b, a Boolean value, if true, it return a generic projective logarithmic form

Description

i1 : l = logarithmicForm(2,{1,1},"a",Projective => true)

o1 = ((a0 a2 a1  - a1 a0 a2 )x  + (a0 a2 a1  - a1 a0 a2 )x )dx  + ((- a0 a2 a1  + a1 a0 a2 )x  + (a0 a1 a2  - a0 a1 a2 )x )dx  +
