I am interested in a tool that takes a simple spice like netlist and generates the symbolic nodal equations and then uses the symbolic math toold box to solve the equations for all nodes.
The closest I could find was the SCAM tool (<http://www.mathworks.com/matlabcentral/fileexchange/3443-scam-a-tool-for-symbolically-solving-circuit-equations>)
While it works well for simple circuit elements it currently does not support dependent voltage sources (VCVS, VCCS, CCVS, CCCS).
Can anyone point me to a tool/utility that supports dependent sources as well?
My goal is to take a circuit netlist (much like SCAM's) and then generate nodal equations using KCL and them solve these system of equations symbolically in MATLAB to get transfer functions.

Another website, https://circuitnav.pythonanywhere.com/, provides an online symbolic circuit analysis tool which uses netlists generated by LTspice, Micro-Cap and Tina-TI.
CircuitNAV also has a good demo at https://www.youtube.com/watch?v=mVk6TzEtQYE, and a tutorial at https://www.youtube.com/watch?v=iLSRXXUobSE.
