An analysis tool for both continuous- and discrete-time control systems. -Includes a parameter so

What is it?
    -A fully automated flowgraph (signal flow graph) analysis tool using 
     Matlab抯 symbolic and control system toolbox. 
    -A tool for generating one or several transfer functions for a given 
     control system.
    -An analysis tool for both continuous- and discrete-time control systems. 
    -Includes a parameter solving tool

Introduction
    From a simple textual nodelist model the user can easily generate one or 
    several transfer functions between any nodes and apply the result 
    to control system analysis. Such a versatile tool can be applied to 
    filter design, delta-sigma modulator analysis or even reflection 
    analysis s-parameter measurements in RF techniques and in optics. 
    Some design examples are attached to the package and also presented in the manual.

Instructions
    -Unpack ZIP-file and extract the file examples.tar in the same directory.
    -Read the manual.
    -Study the demo (flowdemo.m)
    -See what's in the *.flw files.
    -See help for flow_tf.m.
    -Output transfer function(s) are struct arrays,
     so typing e.g. H.sym{1} shows the result (see the demo).
