MATLAB: Cd funtion

From Loren Shure's Blog on Writing Deployable Code by guest-blogger Peter Webb:

Don't rely on the current directory (cd) or changes to the MATLAB path (addpath) to control the execution of M-files. The path of a deployed application is determined at compiled time, and remains forever fixed. The current directory is never on the path in a deployed application. In the code below, cd-ing to the stringFcns directory does not make stringFcns/add shadow mathFcns/add. The order of these functions at runtime depends on what their order was at compile time. This causes errors.

MATLAB: If i have poles and zeros of a transfer function, how to obtain this transfer function ??

transfer_function = tf( zpk(ListOfZeros, ListOfPoles, ListOfGains))
