nullSpace -- find the null space of a mutable matrix

• Usage:

  nullSpace m

• Inputs:
  • m, a mutable matrix, over RR or CC
• Outputs:
  • a mutable matrix, a mutable matrix whose columns span the null space of m

i1 : m = mutableMatrix {{1.p500,1},{-2,-2}}

o1 = | 1  1  |
     | -2 -2 |

o1 : MutableMatrix

i2 : nullSpace m

o2 = | 1  |
     | -1 |

o2 : MutableMatrix

i3 : precision oo

o3 = 500
