Access transfer function data. Argument sys is not limited to transfer function models. If sys is not a transfer function, it is converted automatically.
Inputs
Any type of LTI model.
For SISO models, return num and den directly as column vectors instead of cells containing a single column vector.
Outputs
Cell of numerator(s). Each numerator is a row vector containing the coefficients of the polynomial in descending powers of the transfer function variable. num{i,j} contains the numerator polynomial from input j to output i. In the SISO case, a single vector is possible as well.
Cell of denominator(s). Each denominator is a row vector containing the coefficients of the polynomial in descending powers of the transfer function variable. den{i,j} contains the denominator polynomial from input j to output i. In the SISO case, a single vector is possible as well.
Sampling time in seconds. If sys is a continuous-time model, a zero is returned.
