Linear circuit simulation in Matlab

This program calculates the transfer functions and noise of linear circuits composed of passive components and opamps. It is essentially a re-implementation in MATLAB of the circuit simulation portions of LISO.

Motivations:

• Learn how LISO works
• Simulate circuits in a 100% pure Matlab environment without the need to call an external executable
• Embed the simulation in a higher-level numerical computing environment with scripting, plotting, and optimization routines.
• Idea for future: Can we also use the symbolic computing toolbox to get symbolic transfer functions for simple circuits?

Features that currently work:

• Parses LISO input file
• Parses LISO opamp library
• Currently understands resistors, capacitors, and opamps.
• Produces resulting transfer functions and noises, agrees with LISO for test cases applied so far.

Not yet implemented:

• Only does voltage-to-voltage transfer functions (no 'current' inputs or outputs)
• None of LISO's other fancy features (fitting, etc)
