6.5.20 Solving au+bv=c in ℤ: iabcuv

The iabcuv solves a linear Diophantine equation in two variables.

• The iabcuv command takes three arguments:
  a, b and c, integers.
• iabcuv(a,b,c) returns the list [u,v] where au+bv=c.

Note that c must be a multiple of gcd(a,b) for the existence of a solution.
