Zero Order Hold with variable time step

Level-2 M-file S-function that acts as a ZOH sampler with sample times specified as a block input.

Description

This submission demonstrates how to write a level-2 M-file S-function with a variable sample time.

The block samples and holds an input signal were the inter-sample period is specified by another input signal (and may vary from time period to time period).

Each step size must be positive or an error is thrown.
