intersect(RRi) -- intersection of input intervals

• Function: intersect

• Usage:

  J = intersect(I,...)

  J = intersect(I,...,Precision => prec)

• Inputs:
  • I, a real interval,
• Optional inputs:
  • Precision => an integer, default value -1, specifies the desired precision of the output, a value of -1 uses the minimum precision of the inputs.
• Outputs:
  • J, a real interval,

i1 : intersect(interval(1,3),interval(2,4))

o1 = [2,3]

o1 : RRi (of precision 53)

i2 : intersect(interval(1,2+3*ii),interval(2*ii,3+2*ii))

o2 = [1,2]+[2,2]*ii

o2 : CCi (of precision 53)
