ContPoleZero

This block implements, when activated at a fixed rate, a SISO linear system represented by its rational transfer function. The transfer function must be proper, meaning that the degree of the numerator must not exceed that of the denominator.

Description

The ContPoleZeroblock implements a continuous-time, single-input, single-output (SISO) linear system that is defined by the poles and zeros of its rational transfer function.

The transfer function is defined by a gain (K), a numerator of the form product(s-zi) with zi ith pole, and a denominator of the form product(s-pi) with pi ith pole. The input and output may be of arbitrary but equal size, in which case the SISO system is applied element-wise.
