Examples of DSP.filter.iir.Complex.times()

DSP.filter.iir.Complex.times()
Multiplies this Complex number by another Complex number. Does not alter the value of this Complex object. @param c The other Complex factor. @return New Complex object containing the product.

  public Complex evaluate( Complex c ) {
    
    Complex retval = new Complex( a[order] );
    
    for ( int i = order-1;  i >= 0;  i-- ) {
      retval = retval.times(c).plus( a[i] );
    }
    
    return retval;
  }
