trunc

PURPOSE

TRUNC Truncate the exponents and coefficients of a fractional-order transfer function.

SYNOPSIS

function G1 = trunc(G, na_acc, a_acc)

DESCRIPTION

TRUNC Truncate the exponents and coefficients of a fractional-order transfer function.

      Usage: G1 = trunc(G, na_acc, a_acc)
      where       G - initial system
                  na_acc - exponent accuracy (i.e. 1e-2 means 2 decimal
                  places)
                  a_acc - coefficient accuracy
