[[phi,,,,w] = phasez(sysobj,,,,n)returns the phase response of the filter System object and the corresponding frequencies atnpoints equally spaced around the upper half of the unit circle.
当。。。的时候'算术'input argument is specified as'固定的'过滤对象的系数的数据类型设置为“与输入相同的单词长度”,算术分析取决于系统对象是解锁还是锁定。
unlocked –– The analysis object function cannot determine the coefficients data type. The function assumes that the coefficients data type is signed, has a 16-bit word length, and is auto scaled. The function performs fixed-point analysis based on this assumption.
