balance:
Syntax: balance ( a )
Description:
Balance uses the LAPACK subroutines DGEBAL and ZGEBAL to
balance the input matrix so that the row and column norms are
approximately equal.
balance() returns a list with elements `t' and `ab'.
ab = inv(t)*a*t
And ab is the balanced matrix.
Only square matrices are allowed.
