Matlab pole of transfer function
WebIf poles can prove that the input does not have poles (in the specified interval or complex plane), it returns empty without issuing a warning. a and b must be real numbers or … WebCommands to Create Transfer Functions. For example, if the numerator and denominator polynomials are known as the vectors numG and denG, we merely enter the MATLAB command [zz, pp, kk] = tf2zp (numG, denG). The result will be the three-tuple [zz, pp, kk] , which consists of the values of the zeros, poles, and gain of G (s), respectively.
